Question

find three consecutive numbers such that the sum of the first and second is 15 more than the third​

Answer 1

Step-by-step explanation:

let the 3 consecutive no.s be

x,x+1,x+2

the sum of the 1st and2nd is 15 mote than the 3rd

therefore,

x+x+1+15=x+2

2x+16=x+2

2x-x=2-16

x=-14

therefore the 3consecutive no.s be

1st no.=x

=-14

2nd no.=x+1

=-14+1

=-13

3rd no.=x+2

=-14+2

=-12
