x + x + 2 + x +4 = 57
3x + 6 = 57
3x = 57 - 6 =51
x = 51/3 = 17
first number = 17
second number = 17 +2 = 19
third number = 17 + 4 = 21
3x + 6 = 57
3x = 57 - 6 =51
x = 51/3 = 17
first number = 17
second number = 17 +2 = 19
third number = 17 + 4 = 21

hey!! here's Ur answer
let the 1st no. be x and 2nd one be x+1 and 3rd be x+2
a/q x+x+1+x+2=57
3x+3=57
3x=54
x=18
So now we got the even no. So it's previous one is odd. which is 17
so we got the no. 17 so it's consecutive odd is 19 and next to it is 21..
it's correct answer .. u may verify it.
