Sagot :
You have to decrease 8 from each number:
72 - 8= 64
64 - 8= 56
56 - 8= 48
48 - 8= 40
========
40 - 8= 32
32 - 8= 26
26 - 8= 18
18 -8= 10
10 - 8= 2
72 - 8= 64
64 - 8= 56
56 - 8= 48
48 - 8= 40
========
40 - 8= 32
32 - 8= 26
26 - 8= 18
18 -8= 10
10 - 8= 2
The rule that is used in this pattern is x-8, where x must be subtituted by the given number.
Ex.
(72)-8=64
(64)-8=56
(56)-8=48
(48)-8=40
Ex.
(72)-8=64
(64)-8=56
(56)-8=48
(48)-8=40
