Question

if the sum of five consecutive number is 60 then first number is

Answer 1

Let one of the nos. be x then others are x+1,x+2,x+3 & x+4

We are given, x+x+1+x+2+x+3+x+4 = 60
                            so, 5x+10 = 60
                              so, x = 10

So, Numbers 10,11,12,13,14 

Answer 2

x+x+1+x+2+x+3+x+4=60
5x+10=60
5x=50
x=10

First number is 10
