To find:- the missing number of 9?3

Solution:-

 4 3 2

if we add the first and last number and divided the answer by 2 then we get the middle number =(4 + 2)/2= 6/2 = 3

 5 3 5 1 1

if we add the first and last all numbers and divided the answer by 2 then we get the middle number =(5 + 3 + 1 + 1)/2 = 10/2 = 5

 6 1 2 8 3 3 1

if we add the first and last all numbers and divided the answer by 2 then we get the middle number =(6 + 1 + 2 + 3 + 3 + 1)/2= 16/2 = 8

  7 2 8 4 3

if we add the first and last all numbers and divided the answer by 2 then we get the middle number = ( 7 + 2 + 4 + 3)/2= 16/2 = 8

  9 ? 3

if we add the first and last number and divided the answer by 2 then we get the middle number =  ( 9 + 3)/2= 12/2= 6
