Find the midpoint between two points on a coordinate plane whose coordinates are (5, 7) and (-3, 1). (2, 8) (1, 4) (8, 8) (4, 4)

What is the sum of the geometric series in which a1 = 7, r = 3, and an = 1,701? hint: cap s sub n equals start fraction a sub one left parenthesis one minus r to the power of n end power right parenthesis over one minus r end fraction comma r ≠ 1, where a1 is the first term and r is the common ratio
