The average of first 101 even numbers is

Correct option is A

Given:

Average of first 101 even numbers is

Formula Used:

Average = $$\frac{\text{First term} + \text{Last term}}{2}$$​​

Solution:

First even number = 2

101th even number = 2 × 101 = 202

Average = $$\frac{2 + 202}{2} = \frac{204}{2} = 102$$  

Alternate Solution:
Average of first n even numbers = (n + 1)
Total even numbers (n) = 101
=> Average = n + 1 = 101 + 1 = 102
