Answer:
-4
Step-by-step explanation:
The general, nth term, of a sequence is given by the formula:
[tex]a_n=18-2n[/tex]
We can plug in n = 1 to find the first term, thus we have:
[tex]a_1=18-2(1)\\a_1=16[/tex]
We can plug in n = 2, to the find the 2nd term, which is:
[tex]a_2=18-2(2)\\a_2=14[/tex]
Similarly, to get 11th term, we simply plug in n = 11 into the general term rule. so we have:
[tex]a_n=18-2n\\a_{11}=18-2(11)\\a_{11}=18-22\\a_{11}=-4[/tex]
11th term is -4
