Solution
1. b. This is a simple addition series. Each number increases by 2.
2. b. This is a simple subtraction series. Each number is 6 less than the previous number.
3. c. This is an alternation with repetition series in which each number repeats itself and
then increases by 7.
4. a. This is a simple subtraction series. Each number is 35 less than the previous number.
5. d. In this addition series, 1 is added to the first number; 2 is added to the second number; 3
is added to the third number; and so forth.
6. d. This is a simple addition series with a random number, 8, interpolated as every other
number. In the series, 6 is added to each number except 8, to arrive at the next number.
7. a. This is an alternating addition and subtraction series. In the first pattern, 10 is subtracted from each number to arrive at the next. In the second, 5 is added to each number to arrive at the next.
8. b. This is an alternating number subtraction series. First, 2 is subtracted, then 4, then 2, and so on.
9. c. In this simple alternating subtraction and addition series; 1 is subtracted, then 2 is added, and so on.
10. d. This alternating addition series begins with 3; then 1 is added to give 4; then 3 is added
to give 7; then 1 is added, and so on.
11. a. This is a simple alternating subtraction series, which subtracts 2, then 5.
12. c. In this alternating repetition series, the random number 21 is interpolated every other number into an otherwise simple addition series that increases by 2, beginning with
the number 9.
13. b. In this series, each number is repeated, then 13 issubtracted to arrive at the next number.
14. c. This is a simple multiplication series. Each
number is 3 times more than the previous number.
15. a. This is a simple division series. Each number is divided by 5.
