Answer 1

-121 is your answer for this question

Hope it helps

Answer 2

Answer:

The given sequence is 9, 4, –1, –6, –11,...

Here,

First term (a) = 9

Common difference (d) = a2 – a1 = 4 – (9) = –5

Now,

a27=a+(n−1)d

     =9+(27−1)(−5)  

   =9+(26)(−5)  

   =−121

Hence, the 27th term of the progression is –121.
