    Take the input , divide it by 2 and then add 4.



    ( 12 / 2 ) + 4 = 6 + 4 = 10




    ( ? / 2 ) + 4 = 16 Mulitiply both sides with 2

    ? + 8 = 32

    ? = 32 - 8 = 24



    ( 32 / 2 ) + 4 = 16 + 4 = 20



    ( 62 / 2 ) + 4 = 31 + 4 = 35



    ( 70 / 2 ) + 4 = 35 + 4 = 39



    ( 86 / 2 ) + 4 = 43 + 4 = 47


    So, the rule is :

    Take the input , divide it by 2 and then add 4.



    Inut Output:

    12 10

    24 16

    32 20

    62 35

    70 39

    86 47
