Each term is twice the preceding term
Thus it is a geometric progression of the form 2%5En
Just using 2%5En would give 2, 4, 8, 16, ...
Comparing this sequence to the given one,
we find we need to divide every term by 8 to make it work with the given sequence, so the
nth term is given by %282%5En%29%2F8
