Average Tricks

What is an average?

In simple terms, averages usually refer to the sum of given numbers divided by the total number of terms listed.

Averages = (sum of all terms)/ number of terms
Average is the estimation of the middle number of any series of numbers.

For example average of 1,2,3,4, 5 is 3.
Average can be calculated by sum of all numbers divided by the total number of numbers
Average of  1,2,3,4,5= (1+2+3+4+5)/5 = 15/5 = 3
Which is also the middle number of the series , from here we can also say that in an A.P. i.e arithmetic progression the middle term is the average of the series .
