what is the 12th term in the sequence?

a_n=−16+2n

enter your answer in the box.
a_12=

Easy, sub 12 for n
a12=-16+2(12)
a12=-16+24
a12=8

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.
