Average of 6 consecutive even numbers is 221. Find the value of highest even number.

Let the 6 consecutive number be (x - 4), (x - 2), (x), (x + 2), (x + 4) (x + 6)

The sum of 6 consecutive number = 6x + 6 = 6(x + 1)

The average of 6 consecutive number = 6(x + 1)/6

⇒ (x + 1) = 221

⇒ x = 220

Then, the highest even number = 220 + 6 = 226
