The sum of two consecutive integers is the year of your birth.what is the larger integer?

Question

Can someone answer this please.

Answer 1

Yes, Mark is correct - your year of birth must be odd since, the integer (n) and the consecutive one is (n +1).

so n + (n+1)= year of your birth

2n  + 1= year of birth. 

But the year of birth must be odd so you can subtract one and still divide by two to get an integer.

For me, I was born in 71.

2n+1=71

2n=70

n=35, n+1=36

Let's say you were born in 99

2n=98

n=49 n+1=50
