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.
Some types of series are - leaving a given no. of numbers, squares of numbers, adding the two given numbers to get the next number etc.

A series would mainly be of 4 types.
1) Addition/ Subtraction: The series would be addition or subtraction of a value(any number) to the previous or next number. Eg: 1, 3, 5, 7, _
2) Multiplication/Division: The series would be multiplication or division of a value to the previos or next number. Eg: 1, 2, 4, 8, _
3) Layered Addition/ Subtraction: Similar to addition or subtraction, except that in this type, you would have to add or subract the intermitent value. Eg: 18, 27, 49,_
4) Combination of any or all the above 3 types. Eg: 45030, 9000, 1795, 355, _
Ans is : 68. Method : 9000*5+30 = 45030. 1795*5+25 = 9000 and so on...
