Introduction
Number Order and Symbol Series is a fundamental topic in logical reasoning. It involves identifying patterns and positions of various symbols in a given sequence.
Explanation Step by Step
A series is a sequence of symbols like $, #, @, %, etc. To solve these problems, one must carefully observe the order from left to right and identify recurring patterns or specific positions.
Sub-topics
Symbols
Focusing on the arrangement of non-numeric characters to determine frequency and sequence.
Examples
Example 1
Tricks and Shortcuts
Always mark the symbols you have counted. Remember that 'to the left of' means moving towards the start of the series, and 'to the right of' means moving towards the end.
Common Mistakes
Confusing 'left' and 'right' directions or missing a symbol while counting a long series.
Practice Questions
Easy Questions
- Series: @ @ # @ @ #. How many times does '#' appear?
- In the series * & * & * &, what is the first symbol from the left?
- Count the total number of symbols in: $#$ # $.
Medium Questions
- Series: % % ^ % % ^. How many times is '^' preceded by '%'?
- Find the 5th symbol from the right in the series: @ # $ % & * +.
- Which symbol appears most frequently in: @ # @ $ @ # @?
Hard Questions
- In the series $ # @ $ # @ $, find the symbol which is exactly between the 2nd and 6th position.
- If every second symbol is removed from the series * # * # * #, what will be the new series?
- How many symbols are there between the first and the last '@' in: @ # $ % @ & @?
Revision Summary
Mastering symbol series requires careful observation and practicing directional counting (left and right).
