Question

HELP ME ASAP!!

Write a rule for the nth term of the geometric sequence using the given information: a1= 5 and r=2

Answer 1

`\huge A (n) = 5 ({2})^(n - 1) \\`

Explanation:

The nth term of a geometric sequence is given by

`A(n) = a _ 1( {r})^(n - 1)`

a1 is the first term

r is the common ratio

From the question we have the final answer as

`A (n) = 5 ({2})^(n - 1)`

Hope this helps you
