A.) What is the value of a3? b.) Is the sequence arithmetic or geometric? Explain why.

c.) What is the common difference or the common ratio?

d.) What is the explicit formula of the sequence?

e.) What is a29?

hello! just here for points! though i wish i knew!

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
