Directions :
Number series questions measure your ability to reason without
words. To answer these questions, you must determine
the pattern of the numbers in each series before you will
be able to choose which number comes next. In each series, look for the degree and
direction of change between the numbers. In other
words, do the numbers increase or decrease, and by
how much?
