ALPHA-NUMERIC SERIES
Alphabet Test
● Arranging the general alphabetic letters which are given in jumbled or word form in the
sequence is called an arrangement.
● When two or more patterns of letters including number or symbol occurring equally and making
some pattern is called pattern of words or letters in general.
Points to Remember
● ‘A’ Preceded by ‘B’ → B A
● ‘A’ Followed by ‘B’ → A B
● ‘A’ Precedes ‘B’ → A B
● ‘A’ Follows ‘B’ → B A
● Vowel → A, E, I, O, U
● Consonant → B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z.
● Prime Numbers → A number which is not divisible by any number except 1.
Example: 2, 3, 5, 7, 11, 13, 17, 19, 23, etc.
● Even Numbers → A number which is divisible by 2.
Example: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, etc.
● Odd Numbers → A number which is not divisible by 2.
● Example: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, etc.
Number Series (Group Based)
● In this pattern, group of numbers are given, and the multiple operations will be asked to
perform in the questions for example, addition, multiplication, interchanging of digits, etc.
Series: 567 289 376 189 852
Q. If 1 is added to the 2nd digit of each number and then positions of the first and last digits are
interchanged, which of the following will be the highest number?
A. Given series: 567 289 376 189 852
Adding 1 to the 2nd digit: 577 299 386 199 862
Now, interchange the first and last digit: 775 992 683 991 268
So, 992 is the highest number which comes from 289.
Trick
● In the Question, highest number after interchanging first and last digits is asked, so we don’t
