Can someone please help me with this? Evaluate the sum (n¦0)-2(n¦1)+4(n¦2)-8(n¦3)+…〖-2〗^n (n¦n) for n=3&4. After I find the sum I need to use the binomial theorem to verify my findings.
So for n=3 I got -1 and for n=4 I got 1. I noticed that when I was solving the (n¦n) part I would get the numbers from Pascal’s triangle for the corresponding rows. Does this have anything to do with the question?
