Question

the sum of 5 consecutive numbers are 85. Find the number

Answer 1

let,

1st number= x

2nd number= x+1

3rd number= x+2

4th number= x+3

5th number= x+4

x+x+1+x+2+x+3+x+4= 85

5x+10=85

5x= 85-10

5x= 75

x= 15

so,

numbers will be

15

16

17

18

19

Answer 2

Let the numbers be x,x+1,x+2,x+3,x+4,
sum:-
x+x+1+x+2+x+3+x+4=85
5x+10=85
5(x+2)=5×17
x+2=17
x=17-2
x=15
=>x=15
x+1=15+1=16
x+2=15+2=17
x+3=15+3=18
x+4=15+4=19
