Answer:
24.
Step-by-step explanation:
You would make an equation.
Since it says even, all of the numbers in that equation would be added by an even number. This would be the equation,
n + n+2 + n+4 = 78
3n + 6 = 78
3n = 72
n = 24
Plugging that back into the equation, it'd be
24, (24+2), (24+4)
Three integers: 24, 26, 28. 26 is the smallest of the three.
