... 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

I 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..?)

Also... first terms, 21 = 1, second terms: 42 = 2, so you DO get the original series back, and it does NOT equal 1.

You are subtracting sets of different cardinality. That's like adding unlike terms, you can't do it.
