4. If the pattern below continues, what number likely comes next? 9, 12, 15, 18, 21, ?

24

Step-by-step explanation:

The pattern is +3. What I mean is every next number is 3 more than the last.So, 21 + 3 = 24

I hope this helps!

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
