Answer:
-43
Step-by-step explanation:
By staring at it for a while you can tell that you're losing 5 every step. You can write the succession as [tex]a_n = 32-5n[/tex] (please notice the first terms starts when [tex]n=0[/tex], not 1!). The 16th term happens at [tex]n=15[/tex]:
[tex]a_1_5=32-5(15) = -43[/tex]
