Divisibility of a sum of consecutive integers by a prime number.

Any sum of consecutive integers is divisible by p iff either the sum of terminal terms is divisible by p or the number of terms is divisible by p; terminal terms represent the first and last term and p is a prime number.

Do you want a proof or are you sharing this fact with us ? If it's the latter , I suggest don't make separate notes to share just one or two facts , post a note sharing around 10 -15 facts . That way , everyone will like to go thru your posts :)
