Question 1
What is the missing last term in Terry’s pattern?
Question 2
A pattern of numbers like this is called:
a. a session b. a sequence c. a sentence
Question 3
What is the next term in this sequence?
16.5, 16.6, 16.7, 16.8, 16.9,
Question 4
Choose the correct rule for this pattern:
a. The number of matches is one more than the number of Vs.
b. The number of matches equals the number of Vs.
c.
The number of matches is double the number of Vs.
d. The number of Vs is two more than the numberof matches.
Enter numbers to complete the term-to-term rule for this sequence.
add
The table shows values for the number of V shapes and the number of matches.
Number of V shapes 1 2 3
Number of matches 2 4 6
Complete the position-to-term rule.
Term = × position number
Question 7
What is the third term of the sequence with nth term 7 n– 5?
Question 8
The nth term linking the number of matches to the number of triangles is:
nth term = 2 n+ 1
Use this rule to find the number of trianglesyou would need to make 17 triangles.
Number of matches =
Question 9
What is the third term of the sequence with position-to-term rule 4 n+ 1?
Question 10
A position-to-term rule allows you to calculate any particular term of a sequence quickly and easily.
a. True b. False
Note how the number of matches increases each time the pattern changes.
You could say that the increase in the number of matches:
a. is different each time the pattern changes b. can be predicted each time the pattern changes
c. is increased by two each time the patternchanges
d. is unpredictable each time the pattern changes Be sure to select all correct answers.
43 is a term in the sequence 3 n– 2. What is the value of n?
Question 19
A sequence starts 10, 17, 24, …. Fill in the missing number in the nth term rule.
7n +
Question 20
Which one of the following nth term rules describes the sequence 9, 11, 13, …?
a. 9 n+ 2 b. n+ 2 c. 2 n+ 7
Question 21
Fill in the missing number in the nth term rule for the sequence 2, 7, 12, …
n– 3

Output = 3 2
y = 2 x + 4
When the input is 7, what is the output of the function with this equation?
Output =
Find the position-to-term rule for this sequence.
Term = × position number +
Question 25
Complete the table of values and the position-to-term rule for this pattern.
Position number 1 2 3 4
Term 6 11 16 21
