Explanation

Step-by-step explanation:

Let x , x+1, x+2, x+3 , x+4 are first consecutive numbers

Sum of five consecutive numbers = 60 (Given)

=> x+(x+1)+(x+2)+(x+3)+(x+4) = 60

=> 5x + 10 = 60

=> 5x = 60 - 10

=> 5x = 50

/* Divide each term by 5, and we get

=> x = 50/5

=> x = 10

Therefore,

First number = x = 10
