Answer:
624
Step-by-step explanation:
4, 20, 24, 120, 124, 620 ... What's next?
4, 20
the number gets greater so is either addition +16 or multiplication by 5
20, 24
the number gets greater so most likely is addition +4
24, 120
here we see that 24*5 = 120
120, 124
here we see that 120+4 = 124
124, 620
124*5 = 620
Next we have 620, 620+4 = 624
The Rule is *5 , +4
