If the sum of 5 consecutive numbers is 60 then find the average.?
- 5
- 10
- 25
- 60
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
