1. What is the explicit formula for the sequence of even integers? an = 2. a5= 3. What is the explicit formula for the sequence of odd integers? an = 4. a7 =

1. 2n 2. 10 3. 2n - 1 4. 13

Which of the following is the sequence represented by the graph shown?

1, 4/3, 3/2, 8/5, 5/3

Identify the missing term of the sequence: 1, 8, 27, a4, 125, 216, ...

64

A sequence is defined by dividing the term number by the power of 2 raised to the term number. What is the seventh term?

7/128

Describe the rule for the sequence 2, 1, 2/3, 1/2, 2/5, 1/3, 2/7

Divide 2 by n

The explicit rule for the series 0, 1, 2, 3, ... is given by an = n - 1. Shyla's attempt to find the fifth term in the sequence is shown below: Identify Shyla's mistake and find the correct answer.

What to include in the answer. Which did you include in your response? The correct answer is 4. After using the rule for n = 5, she was done. She tried to look for the fourth term after she arrived at 4; however, the problem asked for the fifth term.

Which of the following is the formula for the sequence whose graph is shown below?

an = (-1) n / n2

Which of the following is the graph of the sequence an = 1 + (-1)n?

the first graph

Find the fifth term of an = (-1)n/ 2n-1

-1/9
