Download Solution PDFGiven:
The average of 9 consecutive even numbers is 132.
Formula used:
Average of n consecutive even numbers = (First number + Last number) / 2
Calculation:
Average = 132
⇒ (First number + Last number) / 2 = 132
⇒ First number + Last number = 132 × 2
⇒ First number + Last number = 264
Since these are 9 consecutive even numbers, the difference between the first and the last number is 2 × (9 - 1).
⇒ Difference = 2 × 8
⇒ Difference = 16
∴ The correct answer is option 1.
