Identify a1 and r for the geometric sequence an= -256(-1/4) n-1

The value of the term is -256 and r is -1/4.

In a Geometric Sequence, each term is found by multiplying the previous term by a constant.

The standard formula for finding the nth term of the geometric sequence is;

Where a1 is the first term and r is the common ratio.

The formula for finding the nth term of the geometric sequence is;

The first term of the sequence is;

The second term of the sequence is;

Therefore,

The value of r is;

Hence, the value of the term is -256 and r is -1/4.

Step-by-step explanation:

The geometric sequence is given by :-

, where a is the first term and r is the constant ratio.

The given explicit formula of nth term :-

First term=

Hence,

Second term =

Now,

hence,  

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
