Question

The sum of three consecutive multiples of 6 is 90. Find the number.​

Answer 1

Answer:

Since they are consecutive multiples of 6, they should be in the form 6(n-1), 6(n), 6(n+1). Here we have sum is 90, 6(n-1)+6n+6(n+1)=18n=90. Therefore, n=5. Consecutive numbers are 24, 30, 36.

Answer 2

Step-by-step explanation:

Let the numbers be x,x+6, and x+6+6

A.T.Q.

x+x+6+x+6+6 =90

3x+18 = 90

3x = 90-18

x = 72÷3

x = 24

So the numbers are 24 30 and 36
