Question 848573
common difference:

96 - 69 = 27

69 - 48 = 21

48 - 72 = -24

72 - 27 = 45

Not seeing a pattern.

We try something different.

This is just a stab.

9 + 6 = 15
6 + 9 = 15
4 + 8 = 12
7 + 2 = 9
2 + 7 = 9
?+ ? = 6

|9-6| = 3
|6-9| = 3
|4-8| = 4
|7-2| = 5
|2-7| = 5
|?-?| = 6 

I will say the answer is 60. Seems to fit both patterns.
