Revisit Exponential Functions and Geometric Sequences

Find the next three terms: 4, 12, 36, 108, ...

• 324, 972, 2916

• 972, 2916, 8748

• 405, 1215, 3645

What is the common ratio for the sequence:
28, 14, 7, 3.5...

• 2

• 1/2

• -14

• -7

Find the common ratio: 64, -16, 4, -1, ...

• r = -8

• r = -1/4

Write down the 8^th term in the Geometric Sequence

1, 3, 9, ...

Write the explicit formula for the geometric sequence.

• a_n = 4(3)^n-1

• a_n = 3(4)^n-1

• a_n = -4(3)^n-1

• a_n = 3(-4)^n-1

What is the 14th term of the geometric sequence?

• 14,348,907

• 4,782,969

• 1,594,323

• 45

is the sequence 2, 4, 8,16,,,, a geometric sequence?

Given "a" the first term is negative and "r" the common ratio is positive then all the terms in the geometric sequence will be negative.

What is a, the starting term, for the function: f(x) = 300(1.16)^x?

• 300

• 1.16

• .16

• x

Which of the following functions shows an initial amount of $15 and an increase of 35% each year?

• y = 15(35)^x

• y = 15(1.35)^x

• y = 15(0.35)^x

• y = 35(1.15)^x
