Question

Sum of two consecutive natural numbers is 11. Which are the numbers?
​

Answer 1

Answer:

If the sum of two consecutive natural numbers is 11  then numbers are 5 and 6.

Step-by-step explanation:

Let two consecutive numbers are : x,x+1

Sum of these numbers is  11, then

x+x+1= 11

⇒2x=  11 - 1

⇒2x=10

x = 5

So, the consecutive natural numbers are 5 and 6.

Answer 2

Given: The sum of two consecutive natural numbers is$11$.

We have to find the numbers.

• To find the numbers we express them as random variables, compute their sum and equate it to the given sum.
• On solving the equation formed we get the values of the consecutive numbers.

We are solving in the following way:

We have,

The sum of two consecutive natural numbers is$11$.

Let assume the two consecutive natural numbers be$x,x+1$.

From the given statement we can write:

$=>x+x+1-11\\=>2x+1=11\\=>2x=11-1\\=>2x=10\\\\=>x=\frac{10}{2} \\\\=>x=5$

So, the two consecutive natural numbers will be:

$=>x=5\\=>x+1=>5+1=6$

Hence, the two consecutive natural numbers are$5\ and\ 6$.
