Struggling with sequence and series questions? This Number and Letter Series reveals the hidden patterns in number and letter series to boost your logical reasoning skills and test scores.


		Number Series Questions 1

Number and Letter Series

The number and letter series are used to assess a candidate’s ability to interpret mathematical expressions accurately and within the given time frame. Number and letter series are sequences in logical reasoning where elements (numbers or letters) follow a specific, hidden pattern or rule. Number series use mathematical rules like addition or squares, while letter series rely on the position of letters in the alphabet or other alphabetic patterns. Both types of series are common in aptitude tests and require identifying the underlying logic to predict the next term or a missing term

Addition Case

Some digits are added in a series that is hidden, and you are asked to find out the next figure in the series. This series is gradually increasing.

Subtracting Case

In this case, some digits are subtracted from the series, and you are asked to complete the series by inserting the missing figure. This series is gradually decreasing.

Adding and Subtracting Case

In this question, some digits of numbers are added and subtracted in the same series jointly, which affects the structure, of easier to find the right answer by paying some attention to the series.

Multiplying Case

In this case, some digits are being multiplied in ascending order to make a sequence.

Letter Series

A letter series is a sequence of letters that follows a logical rule or pattern.

Alphabetical Order

Letters appear in their standard alphabetical sequence (e.g., A, B, C, D).

Skipping Letters

Certain letters might be skipped (e.g., A, C, E, G, which skips every other letter).

Positional Value

The position of a letter in the alphabet (A=1, B=2, etc.) can be used as a basis for the pattern.
