Suppose you are given a question as given below:
Find the average of 5,7,9,11,13?
Sol. Whenever you are given a question like the one above:
Here is a very simple trick for this type of questions.
In this type of questions, first look for the difference of numbers. Since the difference is constant throughout i.e. 2. And given numbers are odd in numbers i.e. total 5 types of numbers.
Then in this type of questions, the answer is always the middle term i.e. 9 (in above question).
But if the numbers were given even in numbers means there are six numbers like 5, 7, 9 , 11, 13,15. Then the answer is always sum of middle terms or sum of opposite terms divided by 2 i.e. (5+15)/2 or (7+13)/2 or (9+11)/2. The answer is always same. In the above case the average will be 10.

Suppose you are given a question like the one given below:
A batsman in his 10th innings makes a score of 75 and thereby increases his average by 5. What is his average after 10 innings?
Here is the solution:
Let his average after 10th innings be x, then
Total score after 10th innings= 9x + 75 = 10 (x + 5)
So x = 75 – 50 = 25
So his average after 10 innings = x + 5
