Compute the value of 1/5+3/25+7/125+15/625+31/3125+.......
1/5, 3/25, 7/125, 3/125, 31/3125, 63/15625, 127/78125, 51/78125, 511/1953125, 1023/9765625, ...etc.
The "closed form" of the sequence is:
a(n) = 5^(-n) (2^n - 1) (for any term)
∑[ 5^(-n) (2^n - 1), n, 1, ∞] ==It converges to 5 / 12
Thank you!
