Answer: she would be having $64 on the sixth day

Step-by-step explanation:

Each day,she doubles the number of dollars she saved on the previous day. This amount of money that she saves each day is increasing in a geometric progression. The formula for the nth term of a geometric progression is

Tn = ar^(n - 1)

Where

a is the first term of the sequence

r is the common ratio

n is the number of terms

To determine how much she saves on the sixth day,

n = 6

a = 2

r = 2

T6 = 2×2^(6 - 1)

T6 = 2 × 2^5

T6 = 64
