Answer:
26
Step-by-step explanation:
First consecutive even number = x
Second consecutive even number = x + 2
Third consecutive even number = x + 4
Add:
x + (x + 2) + (x + 4) = 78
3x + 6 =78
3x = 72
x = 24
The second number would be 26
The middle number of a sequence of consecutive numbers can be found by dividing the sum by the number of terms. 78 ÷ 3 = 26
