Question

The sum of three consecutive multiples of 3 is 72. Find the numbers? ​

Answer 1

Answer:

The consecutive multiples are 21 , 24 & 27

Step-by-step explanation:

Let the numbers be x , x+3 , x+6 ( adjacent multiples differ by 3 )

sum = 72

therefore ,

            x+x+3+x+6=72

            3x+9 = 72

            3x = 72-9

            3x = 63

            x=63/3=21

            x=21

            x+3=24

            x+6=27

           21+24+27 = 72
