Hello once again. Im really confused with the two sequences and series question. Can somebody please help me ?
1. The 2nd and 4th terms of a geometric series is 36 an 16 respectively. All the terms are positive. Determine the first term.
2. The floowing series is given :
(x-1) + (x-1)2 + (x-1)3
2.1 for which values of x will the series converge ?
Σ(3-4k) = -125
where k =1. determine the value of n.
