Question

Every number is either even or odd ​

Answer 1

Answer:

Therefore, by the inductive hypothesis, n − 1 is either even or odd. If n−1 is even then we observe that n = (n−1) + 1, so n is the sum of an even number and an odd number, hence is odd; if n − 1 is odd then n = (n − 1) + 1 is the sum of two odd numbers, hence is even.
