1.   Write a rule that describes how to create each term of the sequence below.
   
    A. Add 3 toothpicks to the right side to create another 2 squares.
    B. Add 6 toothpicks to the right side to create another square.
    C. Add the same number as the term number to the right side to create another 2 squares.
    D. Add 6 toothpicks to the right side to create another 2 squares.
    Hint

  2.   The following explanation of a rule is for a toothpick sequence. Find the correct rule if n is used to represent the term number and t to represent the number of toothpicks.
   
    A. t = 2n – 1 B. t = 2 + (n – 1)
    C. n = 2 + (n + 1) D. t = 2n + 1
    Hint

  3.   The following explanation of a rule is for a toothpick sequence. Find the correct rule if n is used to represent the term number and t to represent the number of toothpicks.
   
    A. t = 2n – 1 B. t = 2n + (n – 1)
    C. t = 2 + (n – 1) D. t = 1 + 2n
    Hint

  4.   One group of students created a table of inputs and outputs from the What's My Rule? game. Find the corresponding rule.
   
    A. n = 4(m – 3) + 1 B. n = (m – 4) + 4
    C. n = 4m – 2 D. n = 4(m + 3)
    Hint

  5.   One group of students created a table of inputs and outputs from the What's My Rule? game. Find the corresponding rule.
   
    A. y = 1 + x · x B. y =
    C. y = 2x + 6 D. y = x2 – 1
