Math

  1. Use inductive reasoning to predict the next number in the list.

    6, 1, 5, 0, 4, −1, 3, ?

  2. A store orders cases of tomato sauce from a warehouse. The following bar graph shows the number of cases of tomato sauce in the warehouse for the first four months of a year.

    • A bar graph has "Months" on the horizontal axis and "Cases" on the vertical axis.
    • In January the height of the bar is 22.
    • In February the height of the bar is 19.
    • In March the height of the bar is 16.
    • In April the height of the bar is 13.

    Using inductive reasoning, how many cases of tomato sauce will be in the warehouse in May?

  3. Use inductive reasoning to predict the next image in the sequence. (See Example 2 in this section.)

    • Four squares are arranged horizontally.
    • In the first square, on the very left, one horizontal line divides the square into two rectangles of equal size.
    • In the second square, to the right of the first, one horizontal line and one vertical line divide the square into four squares of equal size.
    • In the third square, to the right of the second, three horizontal lines and one vertical line divide the square into eight rectangles of equal size.
    • In the fourth square, on the very right, three horizontal lines and three vertical lines divide the square into sixteen squares of equal size.

  4. Brianna, Ryan, Tyler, and Ashley were recently elected as the new class officers (president, vice president, secretary, treasurer) of the sophomore class at Summit College. From the following clues, determine which position each holds. (See Example 8 in this section.)
