CHAPTER - 3 : NUMBER SERIES (EC, EE, ME, CIVIL) - 2015
NUMBER SERIES
Start off with these simple series of numbers.
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. These questions involve only
simple arithmetic. Although most number series
items progress by adding or subtracting, some
questions involve simple multiplication or division.
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?
