Explanation:

I am thinking of the answer

Answer 2

Explanation:

3×2=6

6×2=12

12×2=24

24×2=48

48×2=96

And so on…

We can see it from another way if we write this sequence (denoted by Un later) in terms of n; where its first term U0=3 and its common ratio r=2:

Un=U0×r^(n)

The following term is the 5th then:

U5=U0×r^(5)=3×2^(5)=96
