Question

average of three consecutive positive numbers is 12. what is the largest number. ​

Answer 1

Let x be one of the three numbers.

Then, three consecutive even numbers are x , (x + 1), (x + 2).

Since , average of these is 12.

=> [x + (x + 1) + (x + 2)] / 3 = 12

= > (x + x + 1 + x + 2) = 36

=> (3x + 3) = 36

=> 3x = 33

=> x = 11

Clearly , the largest of these four numbers is (x + 2)

i.e., 11 + 2 = 13.

Hence, the ans is 13.
