Best ResponseYou've already chosen the best response.0... 4, 8, 16, 32 ... 512 or 4(1), 4(2), 4(4), 4(8), ... , 4(128) or 4(2^0), 4(2^1), 4(2^2), 4(2^3), ... , 4(2^7) S(n) = 4 ∑ 2^k [ k = 0 to n ] ....... = 4 [ 2^(n+1)  1 ] S(7) = 4 [ 2^(7+1)  1 ] ....... = 1020

Best ResponseYou've already chosen the best response.2I hate these! I can't see see what is wrong but obviously there is something as it should total infinity... I would just do the 21 in the bracket and get the same answer... (is it not that there will always be one last term in the positive set of numbers which is much bigger than its negative counterpart in that set, and eventually that is infinity..?)

Best ResponseYou've already chosen the best response.2Also... first terms, 21 = 1, second terms: 42 = 2, so you DO get the original series back, and it does NOT equal 1.

Best ResponseYou've already chosen the best response.0You are subtracting sets of different cardinality. That's like adding unlike terms, you can't do it.
