See Below

Step-by-step explanation:

Trend for line one: (+3)       9,12,15,18,21,24

Trend for line two: (+2)       4,6,8,10,12,14

Trend for line three: (+1 alternating each number) 1,8,2,9,3,10

Trend for line four: (+7 for alternating numbers) 2,11,9,18,16,23

2+7=9

11+7=18

9+7=16

18+7=23

Number: 912-810-310-1623

Let me know if this works, I can revise it if there are any issues. Thanks
