Question

Find the next three term sequence 2,8,32,128

Answer 1

You're just multiplying by 4 so...512, 2,048, and 8,192.

Answer 2

It looks like each time you want another term, you take
the last one and multiply it by 4.

2 x 4 = 8
8 x 4 = 32
32 x 4 = 128 .

So if that's the pattern, then the next three terms are ...

128 x 4 = 512
512 x 4 = 2048
and
2048 x 4 = 8192
