The average of 7 consecutive numbers is 20. The largest of these numbers is
let the consecutive no be x,x+1,x+2,x+3,x+4,x+5,x+6 sum of all consecutive numbers=x+x+1+x+2+x+3+x+4+x+5+x+6= 7x+21=7(x+3) average = (sum of all numbers)/( total numbers) given average=20 20 = (7(x+3))/7 = x + 3 X + 3 = 20 => x = 17 largest number is x+6=17+6=23
