An alpha-numeric series is a sequence of letters and numbers in order. The sequence follows a specific pattern, where the letters are placed in a specific order based on their alphabetical position.
Position refers to the place of a letter or number in the sequence based on its position in the alphabet. The first letter is always placed at the beginning, and the last letter is placed at the end.
Preceded/followed refers to the relationship between a letter and the letter immediately after or before it. For example, in the sequence "A B C D", the letter "C" is preceded by "A" and followed by "D".
Here are some examples of an alpha-numeric series:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 (Numbers)
A, B, C, D, E, F, G, H, I, J, K (Letters)
Mary, Joe, Sarah, Tom, John (Alphabetical order)
By understanding the concepts of position and preceded/followed, we can easily predict the next item in an alpha-numeric series
