Question

N is even integer and 10 < n < 19 What is the arithmetic average of all possible value of n ?

(A) 14
(B) 14.5
(C) 15
(D) 15.5
(E) 30

Answer 1

The arithmetic average of all possible even integer values of n between 10 and 19 is 15. The question asks for the arithmetic average of all possible even integer values of n such that 10 < n < 19.

Step-by-step explanation:

The even integers that satisfy this condition are 12, 14, 16, and 18. To find the average, we sum these numbers and then divide them by the number of values.

Here is the calculation:

• Sum: 12 + 14 + 16 + 18 = 60
• Number of values: 4
• Average (arithmetic mean): 60 / 4 = 15

Therefore, the arithmetic average of all possible even integer values of n between 10 and 19 is 15.
