Hey there!
____________________

Let the first number be x
So the next number be x + 1
And the third number will be x + 2

Now, are given in the question:

x + x + 1 + x + 2 = 90
3x + 3 = 90
3x = 87
x = 29

SO, second number will be x + 1 = 30
and third number will be x + 2 = 31

Ans. 29,30,31

Answer 2

let the three consecutive numbers be x and x+1 , ×+2
3x+3=90
3x=87
x=29
so the numbers are 29,29+1=30,29+2=31
