rate the answer also......please!!!!!!

Answer 2

Answer:

The average of all the 11 consecutive odd numbers is X+4

Step-by-step explanation:

Hey Mate,

Method #1

I will provide you a simple method to Solve that types of questions in a few seconds.

Suppose,

11 Consecutive odd numbers are :

X-6, X-4, X-2, X, X+2, X+4, X+6, X+8, X+10, X+12, X+14.

I can tell u direct the average of those 11 consecutive odd numbers is X+4

If in question consecutive word is use then directly find the mean of the series. In consecutive series the average is equal to mean.

Method #2

Or lets calculate by take sum of all digits,

Average = (X-6, X-4, X-2, X, X+2, X+4, X+6, X+8, X+10, X+12, X+14)/11

Average = (11X + 44 ) / 11             #Take 11 common

Average = 11(X + 4 ) / 11  

Average = X+4.

From Both Methods Average must be same.
