M1T2 Quiz Review

Consider the sequence shown. Describe the pattern.

• adding 2 mangos every time

• multiplying the mangos by 2 every time

• adding 1 mango, then 2 mangos, then 3 mangos

Consider the sequence shown. How many mangos would be in the next two figures of the pattern?

• 5,6

• 10,12

• 16, 32

Which numbers represent a numeric sequence for the given pattern?

• 5,9,13,17

• 1,2,3,4

• 6,10,14,18

What is the recursive formula for the sequence: -2,1,4,7,...

• a_n = -2 +3(n-1)

• a_n = a_n-1 + 3

• g_n = g_n-1 * -1/2

• g_n = g_n-1 - 3

What is the explicit formula for the sequence: 1,4,16,64,...

• a_n = a_n-1 + 4

• g_n = 1(4)^n-1

• g_n = g_n-1 * 4

• a_n = 1 - 4(n-1)

What is the 10th term of this sequence? (Hint: find the explicit formula and use it to calculate a₁₀)

0,2,4,6,8,10,...

• 12

• 14

• 16

• 18

What is the 100th term of this sequence? (Hint: find the explicit formula and use it to calculate a₁₀₀)

0,5,10,15,20,25,...

• 500

• 495

• 250

• 400

Write the first five terms of the sequence: a₁ = 1, a_n = a_n-1 + 9

• 10,19,28,37,46

• 1,9,19,29,39

• 1,10,19,28,37

• 10,19,29,39,49

Write the first five terms of the sequence: g_n = 1(3)^n-1

• 1,3,5,7,9

• 3,9,27,81,243

• 1,4,7,10,13

• 1,3,9,27,81

Write the first three terms of the sequence: an arithmetic sequences with a first term of 0 and a common difference of 0.1

• 0.1,0.2,0.3

• 0,0.1,0.2
