Question

Sum of 3 consecutive numbers is 87, fiind the largest no

Answer 1

Let the numbers of three consecutive numbers be x thus the first consecutive will be x-1 and the last consecutive number will be x+1

As per statement sun of three consecutive numbers is 80 as such

(x-1)+x+(x+1)=87

x-1 +x+x+1=87

3x=87+1-1

3x=87

x=87/3

x=29

Thus the middle number is 29 while it's preceding consecutive number will be 29-1=28

And the succeeding consecutive number will be 29+1=30

Therefore the three consecutive numbers are 28,29 and 30.

The largest no. is 30..
