first represent:
let x = first number
let x+1 = second number
let x+2 = third number
*note: since they are consecutive, the difference between them is 1,, that's why it's x, x+1, x+2
set up the equation and then solve for x:
x+x+1+x+2=90
3x+3=90
3x=87
x=29 *first number
x+1=30 *second number
x+2=32 *third number
so there,, =)
