Geometric Sequence Introduction

Given the pattern (sequence), how do you find the next term?

3, 6, 12, 24,...

• Addition/Subtraction (Arithmetic)

• Multiplication/Division (Geometric)

Is the sequence Arithmetic or Geometric?

64, 16, 4, 1,...

• Arithmetic

• Geometric

What would be the next term?

1, 3, 9, 27,...

• 81

• 45

• 243

• 30

Is this sequence arithmetic, geometric, or neither?
{26, 22, 18, 14, ...}

• Arithmetic
• Geometric
• Neither

What is the common ratio (multiplier) for the sequence:

28, 14, 7, 3.5...

• 2

• 1/2

• -14

• -7

What does r represent?

• Radical

• Common difference

• Common ratio

Find the common ratio for the geometric sequence.

• 10
• 1/2
• 2
• 4

What are the next 3 terms in the following geometric sequence:

512, 256, 128, ___, ___, ___, ...

• 1024, 2048, 4096

• 32, 8, 2

• 64, 32, 16

• 92, 66, 38

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

• r = -8
• r = -1/4
• r = -4
• r = 4

Find the common ratio: 4, -16, 64, -256, ...

• r = -4
• r = 2
• r = -2
• r = 4
