Here is the answer for Question No : 25
Ans : 23
Solution :
Let the starting number be : x
7 consequtive numbers : x , (x+1) , (x+2) , (x+3) , (x+4) , (x+5) , (x+6)
Their Average = x+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)+(x+6)
---------------------------------------- = 20
7
=> 7x+21
------ = 20
7
=> x+3 = 20
=> x = 17
So the 7 consequtive numbers is 17,18,19,20,21,22,23
Largest Number is : 23
