Answer 2

y = 17

Explanation:

Given: Mean of 11, 15, 17, (y + 1), 19, (y–2), 3 is 14.  

Mean = Sum of all terms / number of terms.

So we get:

14 = 11 + 15 + 17 + y + 1 + 19 + y - 2 + 3 / 7

98 = 11 + 15 + 17 + y + 1 + 19 + y - 2 + 3

98 = 64 + 2y

34 = 2y

y = 34 / 2

Therefore y = 17. Hence solved.

So the series will be 11, 15, 17, 18, 19, 15, 3.
