Number And Alphabet Sequence - Number Set
Number And Alphabet Sequence - Number Set
Number/alphabet sequence is a combination of numeric and/or alphabetic characters. Before starting with the questions, let us understand the meaning of 'following', 'followed by', 'preceding' and preceded by'.
In this type of questions, generally a set, group or series of numerals is given and the candidate is asked to trace out numerals following certain given conditions of lying at specific mentioned positions after shuffling according to a certain given pattern.
Example 1 : How many such 5s are there in the following number sequence each of which is immediately preceded by 3 or 4 but not immediately followed by 8 or 9 ?
3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0
(a) None (b) Three (c) Four (d) Five (e) None of these
Solution : As you know, a number which comes after a given number is said to follow it while the one which comes before the given number precedes it. Thus, the numbers satisfying the given conditions may be marked as follows :
3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0
Clearly, there are five such 5s. Hence, the answer is (d).
Example 2: In the series, 6 4 1 2 2 8 7 4 2 1 5 3 8 6 2 1 7 1 4 1 3 2 8 6. How many pairs of successive numbers have a difference of 2 each ?
(a) Four (b) Five (c) Six (d) Seven
Solution : Clearly, the pairs of successive numbers having a difference of 2 can be shown as follows :
Thus, there are six such pairs. Hence, the answer is (c).
How many such 4s are there in the following number sequence each of which is immediately preceded by 8 but immediately followed by 5 ? 3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0 | |||
