Find the sum of each infinite series, or state that the sum doesn'nt exist
1/7+5/14+25/28+

(5/14) ÷ (1/7) = 2.5
(25/28)÷(5/14) = 2.5
From the first three terms I will assume that this is a geometric series with r = 2.5
since r > 1, it will diverge, thus it will not have a sum that can be calculated.
The sum will be infinite.
