In the problem: What Three Even Consecutive Numbers Whose Sum Is 72?

Let x - be the 1st even integer
x+2 - be the 2nd even integer
x+4 - be the 3rd even integer

x+ x+2 + x+4 = 72
3x + 6 = 72
3x = 66
x = 22

22 is the first even integer

to get the 2nd even integer
x+2 = 22+ 2
24 is the second integer

to get the 3rd even integer
x+4 = 22+4
26 is the third even interger

to check
x + x+2 + x+4 =72
22+24+26 = 72
72 = 72

The values are 22, 24 and 26
