Question

find three consecutive numbers whose sum is 48 ?

Answer 1

Let the first number be a

Second number = a +1

Third number = a +2

According to question

a + a +1 + a + 2 = 48

=> 3a + 3 = 48

=> 3a = 45

=> a = 15

First number = 15

Second number = 16

Third number = 17

Answer 2

Let first no. Is x
so 2 no. Is (x+1) and 3 no. Is (x+2)
So sum is 48
x+x+1+x+2=48
3x + 3 =48
3x=45
x=15
So three consecutive no. Are 15 , 16, 17
