Given the geometric Series:
1/5 + 1/25 + 1/125 + .........
(a) Find the next two terms.
(b) Determine if it is possible to find s∞.
(c) If possible, find s∞ and then express this sum using the sigma notation.
Any help guys? I can understand that the next term will be 1/625 and then 1/3125? but I can't understand b and c.
