Given the below sequence:
-1, -3, -5, -7, . .
(a) what are the next 3 terms
(b) is this an arithmetic or geometric sequence?
(c) why?
(d) how would you find the 27th term? find the 27th term. (show your work)

a) The next three terms are -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence

C) The difference of second term and first term is -2 in given sequence so the given sequence is an arithmetic sequence.

d) The 27 th term is -53

Step-by-step explanation:

a)  the given sequence is arithmetic sequence

the difference of second term and first term is -2

given sequence is -1,-3,-5,-7.....

the nth term in arithmetic sequence

First term is a = -1 and difference is d = -2

finding fifth term is

finding sixth term is

finding seventh term is

The next three terms are  -9,-11,-13

The given sequence is -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence.

C) because the difference of second term and first term is -2 so the given sequence is arithmetic sequence.

d) by using nth term formula in arithmetic sequence

a= -1 and d =-2

find 27 t h term :-
