Question

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

Answer 1

↑ Here is your answer ↓ _____________________________________________________________ _____________________________________________________________

Let those numbers be 

$x, x+2, x+4$

Given that

$x + x+2+x+4 = 78$

$3x + 6 = 78$

$3x = 72$

$x = 72/3$

$x = 24$

So, numbers are

$x = 24$

$x + 2 = 26$

$x+4 = 28$

Answer 2

let three consecutive even numbers be x, x+2, x+4
acc to ques
x+x+2+x+4=78
3x+6=78
3x=78-6
3x=72
x=72/3
x=24
So the three no are:
x=24
x+2=24+2=26
x+4=24+4=28
