## Tips to Solve IQ Series & Number Patterns Test

A number pattern is another IQ series test pattern that checks the numerical ability of the candidate. This is used in many entrance exams too under verbal reasoning. So, what is the number pattern? It is a sequence or pattern followed by a series of numbers. This pattern established a common type of relation among the numbers provided in a series. But, these number patterns also follow certain mathematical rules like addition, subtraction, multiplication, or division. You need to carefully analyze the rules used and follow different hypotheses to get your answer.

Let us analyze this number pattern through an example. Like, there is a number series of 1, 4, 7, 10, 13….. So the next numbers given in solutions would be 16, 19, 22, and 25. Here, the right answer is 16 because in this series the numbers jump 3 each time as 13+3 = 16. This way there can be subtraction, or multiplication, and even division patterns. Even there can be example series where the numbers are getting doubled each time.

To solve these types of number pattern questions your arithmetic or mental math must be strong enough. It is indeed necessary to check each type of IQ series provided in the interview or entrance exams as the questions will vary. Moreover, the latest patterns followed nowadays are nothing much but the pattern of the missing numbers. So, you must be abreast of the basics of the number series. This article will help you to know how solve the number pattern questions easily and tell how shortcut tricks can be used.
