Question

Identify the 17th term of a geometric sequence where a1 = 16 and a5 = 150.06. Round the common ratio and 17th term to the nearest hundredth.

Answer 1

ooh

Answer 2

so in this one a is 16

150.06=16*r^4

Answer 3

r = 1.749992711

Answer 4

what does the r stand for?

Answer 5

so the 17 term is

16 * (1.749992711^16) = 123 794.064

Answer 6

r stands for ratio. but it is arbitrary tho.

Answer 7

a17 ≈ 123,802.31
a17 ≈ 30,707.05
a17 ≈ 19,684.01
a17 ≈ 216,654.05

Answer 8

actually if your round r

r = 1.74999271
r = 1.75

so

16 * (1.75^16) = 123 802.31

Answer 9

first one

Answer 10

That was correct! Ty!!!
