Consider a sequence of five odd numbers that follow each other. If their average is 39, what is the value of the largest number in the sequence?
Show answer & explanation
Correct answer: B
Explanation
Let us assume five consecutive odd numbers:
x - 4, x - 2, x, x + 2, x + 4
For consecutive numbers, the average = the middle number
Given,
Average = 39
Therefore, x = 39
The numbers are:
35, 37, 39, 41, 43
The largest number among them = 43
