Question

the sum of three consecutive natural numbers is 51. find the number

Answer 1

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

Since x+x+1+x+2 = 51

=) 3x + 3 = 51

=) 3x = 48

=) x = 48/3
= 16.

Hence three consecutive natural numbers are 16, 16+1 and 16+2.

= 16,17 and 18.

Hope it's helpful to u.

Answer 2

Let's call the 1st integer x. The second integer is therefore x+1 and the third integer is x+2 (this is because they are consecutive integers). These three integers sum up to 51; therefore set up the following equation and solve:

 

x+(x+1)+(x+2)=51

3x+3=51

3x=48

x=16

 

Therefore, the first integer is 16 and the next two integers are 17 and 18. The largest one is 18 and this is the answer.
