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 int

Paul [167]

18,19 and 20 are the integers.

Step-by-step explanation:

Given three integers are;

n, n+1, n+2

According to given statement;

n+(n+1)+(n+2)=57

$n+n+1+n+2=57\\3n+3=57\\3n=57-3\\3n=54\\Dividing\ both\ sides\ by\ 3\\\frac{3n}{3}=\frac{54}{3}\\n=18$

n=18

n+1 = 18+1 = 19

n+2 = 18+2 = 20

18,19 and 20 are the integers.
