number should come next?
Start off with these simple series of numbers. Number a. 404
series questions measure your ability to reason without b. 414
words. To answer these questions, you must determine c. 420
the pattern of the numbers in each series before you will d. 445
be able to choose which number comes next. These
questions involve only simple arithmetic. Although 5. Look at this series: 201, 202, 204, 2 0 7 , . . . What

tracting, some questions involve simple multiplication a. 205
or division. In each series, look for the degree and b. 208
direction of change between the numbers. In other c. 210
words, do the numbers increase or decrease, and by

a. 43 18
This set contains additional, and sometimes more b. 41 44
difficult, number series questions. Again, each ques- c. 37 18
tion has a definite pattern. Some of the number series d. 37 41
may be interrupted by a particular number that e. 38 41
appears periodically in the pattern. For example, in
the series 14, 16, 32, 18, 20, 32, 22, 24, 32, the number 25. 9 11 33 13 15 33 17
32 appears as every third number. Sometimes, the a. 19 33
pattern contains two alternating series. For example,
b. 33 35
in the series 1, 5, 3, 7, 5, 9, 7, the pattern is add 4, sub-
c. 33 19
tract 2, add 4, subtract 2, and so on. Look carefully for
d. 15 33
the pattern, and then choose which pair of numbers
comes next. Note also that you will be choosing from e. 19 21
five options instead of four.
