Question

The following series are geometric series. Determine whether each series converges or not.
For the convergent series, enter the sum of the series. For the divergent series, enter DIV .
Also for each series, enter the first term a and the common ratio r.

(b) sigma n=1 (11^n)/(10^n)

(c) sigma n=0 2/(8^(2n))

(d)

sigma n=1 (pi^n)/(2^(n+1))

e)

sigma n=2 (1/3^(n+1))

(f)

sigma n=1 (-2)^(n-1)/(4^(n-1))

(g) Determine whether the following series is convergent or divergent. If convergent find the sum, and if divergent enter DIV:

4-4/2+4/4-4/8+...=
