Can someone better explain this task and the solution. Thanx. For every integer k from 1 to 10, inclusive, the kth term of a certain sequence is given by (-1)^k+1(1/2^k). If T is the sum of the first 10 terms in the sequence, then T is.. 1 greater than 2 2 between 1 and 2 3 between 1/2 and 1 4 betwe...
