Considering the following alternating series. E(-1)*+1 V7k + 6 k=1 a) An alternating series can be written as ) (-1)*- br or ) (-1)* br, where k=1 k=1 br > 0. Find br for the given series. b) Using b, from part a) find lim b. If the limit is infinite, type infinity or -infinity as appropriate. If the limit does not exist and is not infinity, type DNE.
