Question

the sum of three consecutive even number is 78 find the number​

Answer 1

Step-by-step explanation:

let 3 consecutive even nneed be x , x+2 , x+4 .

there sum is 78.

therefore x + x + 2 + x + 4=78

3x + 6= 78

3x = 78-6

3x = 72

x= 72/3

x= 24

therefore 1st consecutive number is 24.

2nd consecutive number is x + 2 = 24 + 2 = 26.

3rd consecutive number is x+ 4 = 24 + 4 = 28.

hence they are 24 ,26 ,28.
