The sum of two consecutive integers is 119

59 + 60 = 119

Make 119 even by adding 1
120/2 = 60 (this is your first number)
60 - 1 (the 1 you originally added) = 59 (this is your second number)

or

Make 119 even by subtracting 1
118/2 = 59
59 + 1 = 60

This can be used for any number

I’d say letter a..
