What is an alphanumeric series?
A sequence of alphabets, either in a single file or in combination, is defined in the Alphabet Series section. This sequence is put together in a specific order. The candidate must recognize this rule and respond to the questions at the end. Most of the time, an alphabet series or sequence will be present, and you’ll need to figure out what term is missing. Other times, you may be asked to locate a term that is incorrect or does not belong in the sequence.
Alphanumeric is a term that combines alphabetical and numerical characters to describe a collection of Latin letters and Arabic digits or a text made up of these letters and digits. According to Merriam-Webster, the term “alphanumeric” can also refer to other symbols like punctuation and mathematical symbols.
What Are Alphanumeric Characters and What Do They Mean?
Alphanumeric characters are a combination of the alphabet’s. Alphabet twenty-six letters (from A to Z) and the numbers 0 to 9. As a result, alphanumeric characters include 1, 2, q, f, m, p, and 10. Alphanumeric characters include symbols such as *, &, and @.
&AF54hh, jjHF47, and @qw99O are examples of alphanumeric characters made up of a combination of special symbols, numbers, and alphabetic characters.
The letters of the alphabet can be written in either lower or upper case. If case sensitivity is used, it is determined by the context of use.

Example 1: The missing letter in the O, R, U series is:
a) V b) W c) X d) Y e) Z
Answer: The letter O corresponds to the number 15 in the table, while the letter R corresponds to the number 18. You’ll also notice that the letter U is the same as the number 21. As a result, the missing alphabet should be X, which, according to the rule of the sequence, corresponds to the number 24. As a result, the correct answer is c) X.
Example 2: Predict the next number in this sequence: V, A, H,
a) M b) N c) O d) P e) Q
Answer: The difficulty of the question increases as the number of alphabets present decreases. Here you can see that V and A are separated by four alphabets. If we follow the circular order of the alphabet, the difference between A and H is six alphabets. As a result, the next alphabet will have to differ by eight alphabets from H. Q is the letter of the alphabet. As a result, the series is V, A, H, and Q. As a result, the correct answer is s) P.
Example 3: In the following space, there is a sequence of alphabets, one of which is incorrectly placed. Choose the incorrect option from the list below:
a) Q, T, X, C b) F, P, Z, J c) W, U, R, N d) A, L, W, Z
Answer: We’ll have to figure out every sequence’s rule. When you use the table, you’ll notice that guessing the rule becomes much easier. Q = 17; T = 20, X = 24, and C = 29 [circular alphabet order] in the first series, for example. As a result, it forms a series according to the rule. F 6, P 16, Z = 26, and J = 36 are the same as the second option. It’s also in the right order. Let’s look at the third one, which has the following values: W = 23, U = 21, R = 18, and N = 14. As a result, the sequence is incorrect. We should have used O instead of N = 14.
As a result, the only series with an incorrect term should be
Let us take a look. A = 1, L = 12, W = 23, H = 34 are the values.
Conclusion
Alphanumeric series questions are made up of a mix of numbers, alphabets, and symbols, and candidates must answer questions based on the series.
The alphanumeric series generally covers 2-3 questions in the reasoning ability section of various Government exams and is one of the most frequently asked topics.
The alphanumeric series questions are scoring and one of the most common logical reasoning topics, in addition to being simple to answer.
