How to Solve Sequence Sums


Hi, my name is Stefan. Today, I'm going to be speaking on how to solve sequence sums. Let's say for example we have the sequence sum how to add the numbers 1 to 5. Now to solve sequence sums you go by the equation S of N is equivalent to N x N + 1/2. In this case, N is equivalent to 5, so that's 5 x N + 1 which is 6/2 which is equivalent to 15 and we can prove that by going 1 + 2 + 3 + 4 + 5, that's 9 + 6 and that's equivalent to 15. The answers match and that's how you solve sequence sums.
