Question

Given two terms from a geometric sequence, identify the first term and the common ratio: a5= 48 and a11= 3,072.

a1 = 2 and r = 3


a1 = 3 and r = 2


a1 = 2 and r = 2


a1 = 3 and r = 3

Answer 1

Answer: a1 = 3 and r = 2

Explanation:

A geometric progression, also called a geometric sequence, is a sequence of numbers whereby every term after the first is gotten by multiplying the previous one by a fixed and non-zero number that is called the common ratio.

In this geometric progression, a5= 48 and a11= 3,072. To get the first term and the common ratio has been attached.
