Question

Find the common​ ratio, r, for the following geometric sequence.

3, 12, 48, ....

R = __

Answer 1

R= 4.

Explanation:

4 is multiplied by each term to arrive at the next terms which would be 192, 768, 3072 Ect....

I hope that is correct and if it is then I hope it helps.

Answer 2

Answer: the common ratio is 4

Explanation:

A geometric sequence is a sequence of numbers such that each term differ from its consecutive term by a common ratio.

The common ratio is determined by dividing a term by the consecutive term following it. This term must be constant for all the terms. It is also a non zero number.

Looking at the given sequence,the first term of the sequence is 3. The common ratio will be

12/3 = 48/12 = 4

4 is constant throughout
