Question

The average of 5 consecutive numbers is 20. The largest of these numbers is *​

Answer 1

Answer:

The largest of these numbers is 18.

Step-by-step explanation:

Let the numbers be x, x+1, x+2, x+3 and x+4

Average = 20

Therefore, x + x + 1 + x + 2 + x + 3 + x + 4 / 4 = 20

Or, 5x + 10 / 4 = 20

Or, 5x + 10 = 80

Or, 5x = 70

Or, x = 14

Hence, Largest number = x+4 = 14+4 = 18 (ans).
