Question

sum of 3 consecutive numbers is243.find the number​

Answer 1

Step-by-step explanation:

let the three consecutive numbers be 'x', 'x+1' and 'x+2' respectively

= (x) + (x+1) + (x+2) = 243

= 3x + 3 = 243

= 3x = 243 - 3

= 3x = 240

= x = 240 ÷ 3

= x = 80

So the three consecutive numbers are :

x = 80

x+1 = 80 + 1

= 81

x+2 = 80 + 2

= 82

Answer 2

Answer:

Let the three consecutive number be x,x+1, and x+2

ATQ,

x+x+1+x+2 = 243

3x + 3 = 243

3x = 243 – 3

3x = 240

x = 80

1st number = 80

2nd number = 80 + 1 = 81

3rd number = 80 + 2 = 82
