Question

The sum of $2$ consecutive numbers is $13$. Find the numbers.

• A. $6$ and $7$.
• B. $5$ and $7$.
• C. $6$ and $5$.
• D. $7$ and $9$.

Answer 1

Answer: (A)

$6$ and $7$.

Let the two consecutive numbers be $x$ and $x+1$

According to the question

$x+x+1=13$

$2x+1=13$

$2x=13-1$

$2x=12$

$x=\frac{12}{2}$

$x=6$

$x+1=6+1=7$

Therefore the two consecutive numbers are $6$ and $7$.
