a sequence is represented below.
{–5, –25, –125, –625, -3125, ...}
Which recursive notation could be used to represent the sequence?
F. a1 = –5, an = 5an-1
G. a1 = 5, an = –5an–1
H. a1 = –5, an = an-1+ 5
J. a1 = 5, an = an–1 – 5

Answer 1

g

Explanation:

Answer 2

F. a1 = –5, an = 5an-1

Explanation:

a1 = -5 <---- Answer

r = -25/-5 = 5

an = r(an - 1)

an = 5(an - 1) <---- Answer

Hope this helps!
