Question : What is the difference between the average of the first 148 even positive numbers and the average of the first 129 odd positive numbers?
Option 1: 21
Option 2: 20
Option 3: 23
Option 4: 19
Correct Answer: 20
Solution : The sum of the first $n$ even number $=n(n+1)$. The sum of the first odd $n$ numbers $=n\times n$. $\text{Average}=\frac{\text{Sum}}{\text{The total number}}$ The sum of the first 148 even numbers $=148(148+1)=148\times149$ The average of the sum of the first 148 even numbers $=\frac{148\times149}{148}=149$ The sum
