Answer 15

he amount he deposits is a geometric sequence:
1, 2, 4, 8, 16, ...

This is a geometric sequence with a first term of 1 and a common ratio of 2.
a = 1
r = 2

The general formula for the sum of the first t terms of a geometric series is:
S(t) = a(1 - r^t) / (1 - r)

Plug in your values for a and r:
S(t) = 1(1 - 2^t) / (1 - 2)
S(t) = (1 - 2^t) / -1
S(t) = -1 + 2^t
S(t) = 2^t - 1

Answer:
S(t) = 2^t - 1
