Answer: the common ratio is 4
Step-by-step 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
