Let the first number be x, 
So last number will be (x+6)

Average = [x+(x+1)+(x+2)+(x+3)+(x+3)+(x+4)+(x+5)+(x+6)]/7 = 20 

=> (7x+21) = 20*7 
=> 7x = 119
=> x = 17

So largest number= (x+6) = (17+6) = 23

Let the numbers be x, x + 1, x + 2, x + 3, x + 4, x + 5 and x + 6,

Then (x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6)) / 7 = 20.

or 7x + 21 = 140 or 7x = 119 or x =17.

Latest number = x + 6 = 23.
