Correct option is D
Given:
We need to find the average of the first 134 even numbers.
Concept Used:
The nth even number is given by 2n.
The average of the first n numbers can be calculated using the formula:
Average = (Sum of numbers) / (Number of numbers)
Formula Used:
Sum of the first n even numbers = n × (n + 1)
Average = Sum / n
Solution:
The sum of the first 134 even numbers is:
Sum = 134 × (134 + 1) = 134 × 135 = 18,090
The average is:
Average =
Thus, the average of the first 134 even numbers is 135.
