Average of 17 consecutive natural numbers starting with ‘a’ is x. What will be the average of 17 consecutive natural numbers starting with ‘a + 6’?
Show answer & explanation
Correct answer: B
Explanation
Given:
The average of 17 consecutive numbers starting from ‘a’ = x
In a series of consecutive numbers, the average = the middle number
The middle number of the first series = a + 8 = x
The middle number of the second series (starting from a + 6)
= (a + 6) + 8 = a + 14
= (a + 8) + 6 = x + 6
