Write an equation for the nth term of the arithmetic sequence. Then find a10. −6,−9,−12,−15, ...

-33
Sequence: An = −3n − 3
*Plug-In n = 10*
n = -3(10) - 3
n = -30 - 3
n = -33

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.
