Question 1131952: 1: true or false
1000........................................998
(Sigma)7 (3/4)^n. = 63/16 (sigma)(3/4)^n
N=2.........................................n=0
2: compute
10
(Sigma)(1/2)^t
t=0
3: check the formula is correct for k=1,2, and 3
k
(sigma)n^2 = k(k+1)(2k+1)/6
n=0
4: use the formula given in problem 3 to compute the value of
