Question

Find three consecutive positive even numbers whose sum is 90​

Answer 1

Answer:

let the 3 consecutive positive even numbers are are x , x+2 , x+4

x+x+2+x+4 = 90

3x+6=90

3x = 90-6

3x = 84

x = 84/3

x = 28

Answer 2

Step-by-step explanation:

Let the no. be x

then, x+1 and x+2

x + x + 1 + x + 2 = 90

3x + 3 = 90

3x = 90 - 3

3x = 87

x = 87/3

x = 29

hence, x = 29

x + 1 = 29+1 =30

x +2 = 29+2=32
