to clarify: The even number, such as 8, is not the n. You have to divide it by 2 first, then multiply by n+1. so to find the sum of even numbers up to 8, you need 8/2=4, then 4*5=20. n represents the number in the pattern so the formula seems misleading without that information presented more obviously. Again, like the sum of even numbers up to 86 means there are 43 even numbers (because 86/2=43), then you use 43(43+1). I hope that makes sense?
