Question

The average of four consecutive odd
numbers is 16. What is the product of
lowest and highest number?
​

Answer 1

Answer:

7

Step-by-step explanation:

Let those numbers are 2x - 3, 2x - 1, 2x + 1, 2x + 3.

Sum of nunbers = 16

=> (2x - 3) + (2x - 1) + (2x + 1) + (2x + 3) = 16

=> 2x + 2x + 2x + 2x = 16

=> 8x = 16

=> x = 2

Product of lowest and highest is

=> (2x - 3)(2x + 3)

=> (2(2)-3) (2(2)+3)

=> (4 - 3)(4 + 3)

=> 7
