Coursework Help Nth Term!!!
I am confused :confused: :confused: :confused: :confused: :mad:
I am trying to find a formula to link these numbers for a part of my GCSE coursework (i.e nth term) could someone please show me how i can do this??
1 2 3 4 5
3 6 10 15 21....
I know that the numbers underneath are triangle numbers, but i am confused about nth term, and dont know how to work this out.
so far i have done this:
1 2 3 4 5
3 6 10 15 21
3 4 5 6 - Difference
1 1 1 - Difference
But i do not know what these numbers mean? and how you can work out the nth term from it? (does the difference being incosistant then consistant show something? like n+1 or 1n or something? PLEASE HELP!!!)i want to know how i can get the answer! so please show me HOW you can find it!
