please tell the ans if you know ..​

Answer 1

Answer:

let the first number be x

second number be x+1

third number be x+1+1 = x+2

given,

x+x+2 = 36

2x = 36 - 2

2x = 34

x = 17

the three consecutive numbers are x = 17, x+1 =18,

x+2 = 19

Answer 2

Answer:

3 consecutive number's are = 17 , 18 , 19

Step-by-step explanation:

let 3 consecutive number be (x - 1) , x, (x + 1)

sum of 1st and 3rd number = 36

i. e. (x - 1) + (x + 1) = 36

2x = 36

x = 18

so 3 consecutive numbers are :-

1st = (x-1) = (18 - 1) = 17

2nd = x = 18

3rd = (x + 1) = (18 + 1) = 19
