The sum of two consecutive integers can't be an even number, because the one number is even and the other odd.
in this case:
a = first number
b = second number
b = a + 1
a + b = 122
a + a + 1 = 122
2 a + 1 = 122 Subtract 1 to both sides
2 a + 1 - 1 = 122 - 1
2 a = 121 Divide both sides by 2
a = 121 / 2 = 60.5
b = a + 1 = 61.5
Are you sure the sum is = 122?
