Alphanumeric Series
An Alphanumeric Series is a structured sequence consisting of letters of the English alphabet, numerical digits, and special symbols. These elements are arranged according to a specific logical rule or pattern. The primary objective is to identify this hidden rule to find the next term or a missing term in the sequence. Sometimes, you may be asked to count specific elements based on their position relative to others. For example, a question might ask how many numbers are preceded by a vowel.

These are series with gaps like 'a _ b c _ a b _'. To solve these, count the total characters including gaps. Try to divide the total into equal groups of 3, 4, or 5. Look for a repeating pattern in these groups. Example: 'ab_c | ab_c'.
These are series with gaps like 'a _ b c _ a b _'. To solve these, count the total characters including gaps. Try to divide the total into equal groups of 3, 4, or 5. Look for a repeating pattern in these groups. Example: 'ab_c | ab_c'. The missing letter in both groups is likely the same, such as 'd', making it 'abdc'.
This concept involves converting letters into their numerical ranks. For example, the word 'BAG' can be seen as 2-1-7. Knowing these ranks helps you identify if the series is increasing by a fixed number.
This concept involves converting letters into their numerical ranks. For example, the word 'BAG' can be seen as 2-1-7. Knowing these ranks helps you identify if the series is increasing by a fixed number. Example: In the series B, D, F, H, the ranks are 2, 4, 6, 8. The pattern is +2. The next rank is 10, which is the letter J.
This is a counting task based on relative positions. 'A is preceded by B' means the sequence is BA. 'A is followed by B' means the sequence is AB.
This is a counting task based on relative positions. 'A is preceded by B' means the sequence is BA. 'A is followed by B' means the sequence is AB. Example: In the sequence 5 1 4 7 3, how many odd numbers are followed by an odd number? The pairs are (5,1) and (7,3). There are two such instances.
