Given : Average of 3 consecutive even numbers - 18
Find : Largest among three consecutive even numbers.
Solution : Let the three consecutive even numbers be x, x+2 and x+4. The sum of these three consecutive even numbers will be : 3x+6.
As per the question, the average is 18. The mathematical representation will be :
(3x + 6)/3 = 18
3x + 6 = 18*3
3x + 6 = 54
3x = 48
x = 16
The first even number = x = 16
The second even number = x+2 = 18
The third even number = x+4 = 20
Hence, the largest of these numbers is c. 20.
