Hope that this is helpful.
Step-by-step explanation:
7,11,15,19 - 16,20,24,28(add 4 )
7+4=11. 16+4=20
11+4=15. 20+4=24
15+4=19. 24+4=28
12,24,48,96 - 31,62,124,248(multiply 2)
12×2=24. 31×2=62
24×2=48. 62×2=124
48×2=96. 124×2=248
13,15,17,19 - 132,134,136,138(add 2)
13+3=15. 132+2=134
15+2=17. 134+2=136
17+2=19. 136+2=138
3,12,48,193 - 7,28,112,448(multiply 4)
3×4=12. 7×4=28
12×4=48. 28×4=112
48×4=193. 112×4=448
