Maths Proof - Prove Algebraically That The Sum Of Any Two Consecutive Integers Is An Odd Number

In this video you will learn how to prove algebraic that the sum of any two consecutive integers is always an odd number.

To do this call the first number in the sequence n and the second number n+1. Since sum means add this will give 2n + 1. Since 2n is a multiple of 2 then 2n+1 is an odd number.
