Write the first five terms of the sequence defined recursively.

Question

Use the pattern to write the nth term of the the sequence as a function of n. (Assume that n begins with one.)

a₁=4, a_k+1 = -a_k

options

a. a_n = 4n

b. a_n = 4(-1)ⁿ

c. a_n = (-4)ⁿ

d. a_n = (-4)^n-1

e. a_n = 4(-1)^n-1

Answer 1

If the first term is 4 and the second term is the negative of the first term, then what is the second term?

If the third term is the negative of the second term, then what is the third term?

Which of the answer choices matches this pattern?
