Question

A geometric sequence has a first term of 4 and a second term of 12. What is the common ratio ?

Answer 1

Answer:

3

Step-by-step explanation:

Solution,Here,

In geometric sequence,

first term=4

second term=12

common ratio=?

We know that,

common ratio (r) = second term ÷ first term

=12÷4

=3

Hence, the required common ratio is 3.
