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
