input output

12 10
? 16
32 ?
62 35
70 39
86 ?

what's my rule?

1 answer

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
