Question

3. Find three consecutive natural numbers such that the sum of the first and second is 15 more than 3rd no​

Answer 1

Let the first number is x.

other numbers are (x+1), (x+2).

given that sum of the first and second numbers are 39 more than the third number.

x+(x+1)=(x+2)+39

2x+1=x+41

2x-x=41-1

x=40

three numbers are 40,41,42.
