Arithmetic Sequences on FX9750GII

First, understand the nature of a geometric sequence, essentially one notes the multiple that makes the common distance between numbers in a set. That multiple is called the ratio. Here is one of the better explanations: https://www.mathsisfun.com/algebra/sequences-sums-geometric.html

I would suggest practicing an example until you are comfortable with how the formula works. For a deeper look into the formula, you might look up the Khan Academy's discussion of geometric sequences and the formula. But if simply looking for problem solving steps, you can look at the links at https://www.effortlessmath.com/math-topics/geometric-sequences/

There are YouTube videos about geomtric sequencing. If you need more assistance, you might try a few of such. Sadly, nothing about math come easy to me and I might suggest seeing a tutor if it is proving elusive.

I think you need another term to establish an arithmetic sequence.

Using p=2, we have the sequence 5, -1.

Repost with the third term.

Good luck,

Are you trying to find a particular term in the geometric sequence?

For example, in the geometric sequence 2,4,8,16 to find the 15th term we would use the formula a sub n = a sub 1 x r ^(n-1), where a sub n is the nth term of the geometric sequence
a sub 1 is the 1st term of the geometric sequence
r is common ratio between successive terms
n is the term you are looking for

In our example, a sub 1 is 2, r is 2 and n is 15.

a sub n = a sub 1 x r ^(n-1)
a sub 15 = 2x 2(15-1)
a sub 15 = 2 ^ 15
a sub 15 = 32,768

On your calculator, you use the key to the right of x^2 to do x to the nth power.

Good luck.

This is not the kind of material for this site, we are a self help repair and use site for manufactured products.

The syntax is
Sigma ( function (n),index n, starting value of index n, ending value of index n, increment of n).
If you omit the increment of the index the calculator will assume it is equal to 1

Here, We deal with Some Special Products in Polynomials.

Certain products of Polynomials occur more often
in Algebra. They are to be considered specially.

These are to be remembered as Formulas in Algebra.

Remembering these formulas in Algebra is as important
as remembering multiplication tables in Arithmetic.

We give a list of these Formulas and Apply
them to solve a Number of problems.

We give Links to other Formulas in Algebra.

Here is the list of Formulas in
Polynomials which are very useful in Algebra.
Formulas in Polynomials :

Algebra Formula 1 in Polynomials:

Square of Sum of Two Terms:

(a + b)2 = a2 + 2ab + b2
Algebra Formula 2 in Polynomials:

Square of Difference of Two Terms:

(a - b)2 = a2 - 2ab + b2
Algebra Formula 3 in Polynomials:

Product of Sum and Difference of Two Terms:

(a + b)(a - b) = a2 - b2
Algebra Formula 4 in Polynomials:

Product giving Sum of Two Cubes:

(a + b)(a2 - ab + b2) = a3 + b3
Algebra Formula 5 in Polynomials:

Cube of Difference of Two Terms:

(a - b)3 = a3 - 3a2b + 3ab2 - b3 = a3 - 3ab(a - b) - b3
Algebra Formula 8 in Polynomials:


Each of the letters in fact represent a TERM.

e.g. The above Formula 1 can be stated as
(First term + Second term)2
= (First term)2 + 2(First term)(Second term) + (Second term)2

You did not provide a general (n) term. However, I figured it to be something involving n^2. Hence the sum to n terms can be of the form: xn^3 + yn^2 + zn. Using the partial sums: 1, 6 (1+5), and 18 (1+5+12) we can build a linear equations system:
1= x + y +z (n=1)
6 = 8x + 4y +2z (n=2, n^2=4, n^3 = 8)
18 = 27x + 9y + 3z (n=3, n^=9, n^=27)
Solving for x,y,z we get x = 1/2, y= 1/2, z =0
Hence 1+5+12+22+..+ f(n^2)= 1/2(n^3+n^2)

Notice that 6 x -2 = -12, and -48 x -2 = 96. It *seems* as if you get each term in the sequence by multiplying the term before by -2.

*if* this is right, you can get blank by working out :
-12 x -2 = blank.
You then need to check if
blank x -2 = -48.
If so, you've found the answer! If not, check your arithmetic, and look for a different pattern...

WPA requires an group of alpha numeric sequences for encrypting data between the wireless card on the computer and the wireless access point/router.
These sequences are hard to remember when setting up the wireless Access point/router soa passphase is used to generate these alpha numeric sequences, just use any english phrases such as "I love you 2 pieces", then this can be used to configure your wireless card on your computer.
