hi
your answer is here !
Step-by-step explanation:
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.

Answer:
Step-by-step explanation:
let the numbers be x, x+1,x+2,x+3,x+4,x+5,x+6
(7x +21)/7=20
7x+21=20x7
7x+21 = 140
7x= 140-21
7x=119
x=119/7
x=17
hence the numbers are 17,18,19,20,21,22,23
the largest number is 23
