What will be the average of the odd numbers from 1 to 51, both inclusive?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 26.
Number of odd numbers = [(Last term - First term)/Common difference)] + 1
= [(51 - 1)/2] + 1 = 25 + 1 = 26
Sum of 'n' odd numbers = n2
Average = (26)2/26 = 26
