Question

Find the consecutive numbersuch that the sum of the first and second is 15 more than the third?​

Answer 1

Answer:

Step-by-step explanation:

Let x,(x+1),(x+2) are three consecutive natural numbers.

According to the problem given,

The sum of the first and second is 15 more than the third number.

=> x+(x+1)-(x+2)=15

=> x+x+1-x-2=15

=> x-1=15

=> x = 15+1

=> x = 16

Therefore,

Required three consecutive natural numbers are :

x = 16,

x+1 = 16+1 = 17,

x+2 = 16+2 = 18

hope this helped.

Answer 2
