Consider the series ∑n=0[infinity](34)n. The first four terms in the sequence of partial sums for this series are 1, 3/4, 9/16, 27/64 . Enter a comma separated list of numbers (in order). The nth partial sum is Sn=1+3/4+(3/4)2+(3/4)3+⋯+(3/4)n= . Enter a closed-form expression for this sum. The sum of this geometric series is ∑n=0[infinity](34)n=limn→[infinity] (
