The sum of two different odd numbers and an even number could be ...

A) 52

B) 61

C) 65

D) 77

A 52 because two odd numbers together equal an even number, plus an even number makes an even number.

You can represent an even number as 2n where n = a whole number (exg, 0,1,2,3,4, etc)

and odd number is 1 more so it is represented as 2n+1 so

summ of (additinon) of 2 different odd numbers and an even number could be

so 2 different odd numbers could be 2n+1 and 2n+1+2 since odd numbers are 2 apart so

odd+odd+even=2n+1+2n+3+2n=6n+4

we can see that 6n+4=2n+2n+2n+4 and 4=even

remember that even+an infinite number of even number = even so therefor 6n+4=even

we look at the answers and see taht 52 is the only even number

the answer is A, 52
