Question

when two consecutive numbers are added the sum is 31, find the numbers

Answer 1

Answer:

Numbers are 15 and 16

Step-by-step explanation:

Let first number be x

Its consecutive number will x+1

Condition:(x)+(x+1)=31

x+x+1=31

2x=31-1

x=15

Consecutive number=x+1=16

Answer 2

Answer:

Let the first natural number x

Then second natural number = x +1

According to the sum

x + ( x +1 ) = 31

= 2x + 1 = 31

= 2x = 31 - 1

= 2x = 30

= x= 15 .

Hence,

First natural number = 15.

and Second number = 15 + 1 = 16
