Question

18

Select the correct answer.
Identify the correct form of the following geometric sequence.

5 , 35 , 245 , 1,715 , ...

A.
g(x) = 7x + 5
B.
g(x) = 7(5x)
C.
g(x) = 5(7x - 1)
D.
g(x) = 7x + 5

Answer 1

Explanation:

The correct answer is none of the options given. The given sequence is a geometric sequence with a common ratio of 7. The general form of a geometric sequence is g(x) = ar^(x-1), where a is the first term and r is the common ratio. In this case, a = 5 and r = 7, so the correct form of the geometric sequence is g(x) = 5(7^(x-1)).
