Three consecutive integers can be represented by n, n+1, and n+2. If the sum of three consecutive integers is 57, what are the integers?

$18 , 19 , 20$

Explanation:

Sum is the addition of number so the sum of n, n+1 and n+2 can be represented as,

$n + n + 1 + n + 2 = 57$

$3 n + 3 = 57$

$3 n = 54$

$n = 18$

so our first integer is 18 (n)
our second is 19 ,(18+1)
and our third is 20 ,(18+2).
