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.
