For five consecutive integers, the sum of squares of the first three numbers equals the sum of squares of the last two numbers
Let these five consecutive integers be n, N + 1, N + 2, N + 3, N + 4, N2 + (n + 1) 2 + (n + 2) 2 = (n + 3) 2 + (n + 4) 2, and the solution is n = 10 or n = - 2. When n = 10, these five numbers are 10, 11, 12, 13, 14. When n = - 2, these five numbers are - 2, - 1, 0, 1, 2
