Number Series संख्या श्रेणी शार्ट ट्रिक्स 

As we know that various competitive exam having aptitude syllabus; and in this syllabus there are some questions asked from number series sections. For the same we are going to share some most important and very useful short tricks of number series questions in Hindi as well as English language. It is very useful for those candidates who want to solve this number series questions in very short time with accuracy. This post also contain important questions and examples of various tricks which is asked in previous year exams.

Type of Number Series-1

Power Series

a) Square Series:-

                  If  all steps of given series is square or near to square, then this type of series is known as square series.

Example :- In the given number series, which number is not correct ?

               2         5         11         23         48         95         191         383






b) Constant Multiplication and increasing Addition Series:-


                  If in the given series the difference between first and last terms is very large and from there two sequential numbers by multiplying a fix number and then addition of number in increasing form the next number will get, then this type of series is known as constant multiplication and increasing addition series.


Example :- In the given number series, which number is not correct ?
                          3         7         16          38         74         153





c) Increasing Multiplication and constant Addition Series:-

                  If in the given series the difference between first and last terms is very large and from there two sequential numbers by multiplying number in increasing form and then adding a fix number the next number will get, then this type of series is known as increasing multiplication and constant addition series.



Example :- In the given number series, which number is not correct ?

                  7         8         16          52         209         1046         6277



d) Increasing Multiplication and Increasing Addition Series:-


                  If in the given series the difference between first and last terms is very large and from there two sequential numbers by multiplying number in increasing form and then addition of number in increasing form the next number will get, then this type of series is known as increasing multiplication and increasing addition series.



Example :- In the given number series, which number is not correct ?


                           2         3         8         37         112         565



Type of Number Series-5


Multiplication and Subtraction Series


a)Constant Multiplication and Constant Subtraction Series:-

                  If in the given series the difference between first and last terms is very large and from there two sequential numbers by multiplying a fix number and then subtracting a fix number the next number will get, then this type of series is known as constant multiplication and constant subtraction series.



Example :- In the given number series, which number is not correct ?

                     386         192         98         50         26         14         8
