Question

The sum of three consecutive numbers is 45. Find the numbers.

• A. 12, 13, 14
• B. 12, 13, 20
• C. 14, 15, 16
• D. 15, 16, 17

Answer 1

The correct option is C 14, 15, 16

Let $x,x+1,x+2$ be the three consecutive numbers.
$x+(x+1)+(x+2)=45$
$3x+3=45$
Divide both sides by 3,
$x+1=15$
$x=14$
Hence, the given three consecutive numbers are 14, 15 and 16.
