The last problem demonstrated that using the formula sn=a1(1−rn)1−r gave the same answer as adding all 15 days individually.
now it is your turn to use this formula to evaluate the total amount of money received over the 20 days.
remember that a1 is $0.01, the common ratio is 2, and the number of terms in the sequence is 20.
use the formula sn=a1(1−rn)1−r to evaluate the series.
