The sum of two consecutive numbers 122.what is the number

1 answer

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?
