What type of sequence is this: 15, 10, 5, 0, . . .

• Arithmetic

• Geometric

• Neither

• Dumb

Write the rule for this sequence: 15, 10, 5, 0, . . .

• t(n) = -5(15)ⁿ

• t(n) = 15(-5)ⁿ

• t(n) = -15n + 5

• t(n) = -5n + 15

• Arithmetic

• Geometric

• Neither

• Narnia sequence

What type of sequence is this: 10, 14, 19.6, 27.44, . . .

• Arithmetic

• Geometric

• Neither

• it is sequentially sequential

Write the rule for this sequence: 10, 14, 19.6, 27.44, . . .

• t(n) = 10(0.71)ⁿ

• t(n) = 0.71(10)ⁿ

• t(n) = 10(1.4)ⁿ

• t(n) = 1.4(10)ⁿ

Write an arithmetic rule for this situation:

Jonny had $150 in the bank received $5 a week for his allowance.

• y = 150x + 5

• y = 5x + 150

• y = 150(5)ⁿ

• y = 5(150)ⁿ

What is the multiplier for:

A 7% decrease

• 0.93

• 0.07

• 1.07

• 93

What is the multiplier for:

A 12% increase

• 0.88

• 0.12

• 1.12

• 88

Write an exponential ( geometric) rule for:

Lucy owns a house worth $100,000 that increases in value by 4 percent each year.

• y = 4x + 100,000

• y = 100,000x + 4

• y = 100,000(1.04)^x

• y = 100,000(4)^x

Write an exponential ( geometric) rule for:

Rocky owns a motorcycle worth $5000 that depreciates (decreases in value) 6 percent each year.

• y = 5000(6)^x

• y = 5000(0.06)^x

• y = 5000(1.06)^x

• y = 5000(0.94)^x
