Question

no spam plz. ​

Answer 1

Answer:

let 3 consecutive numbers be

x, x+1, x+2

so, their sum will be

x+x+1+x+2 = 720

3x +3 = 720

3x = 720-3

3x = 717

x = 717/3

x = 239

thus three consecutive numbers are

239, 240, 241

hope it helps u

Answer 2

Let the three consecutive numbers be x , (x+1) , (x+2) respectively

according to the question

x+(x+1)+(x+2)=720

x+x+1+x+2=720

3x+3=720

3x=720-3

3x=717

x=717÷3

x=239

the three consecutive numbers will be 239 , (239+1) , (239+2)

so 239 , 240 , 241 are the required three consecutive numbers.
