Question

what is the sigma notation form of 1 + 2 + 6 + 24 + 120 + 720?

Answer 1

First you need to come up with a pattern for those numbers. There needs to be a function f(n) such that f(1)=1, f(2)=2, f(3)=6, f(4)=24, f(5)=120, and f(6)=720. Can you think of a function that does that? A little hint: its rather exciting!!!!!

Answer 2

clever hint joemath :)
