Short Answer 
The answer outlines a method for identifying an anomalous number in a list by using divisibility patterns. In the provided example, all numbers except for 2 are divisible by 4, making 2 the unique outlier.
Step 1: Understand the Number System
A number system is a structured way of writing and expressing numbers. It allows us to perform various mathematical operations and communicate numerical values effectively. Different number systems can represent numbers in various forms, such as decimal, binary, or hexadecimal.
Step 2: Identify the Divisibility Pattern
In the given list of numbers (2, 20, 4, 8, 300), we need to look for a common divisibility pattern. Here, we observe that all numbers except for one are divisible by 4. To determine this, we can perform division:
- 20 ‚à ö‚à ë 4 = 5
- 4 ‚à ö‚à ë 4 = 1
- 8 ‚à ö‚à ë 4 = 2
- 300 ‚à ö‚à ë 4 = 75
Step 3: Identify the Anomalous Number
By analyzing the results, we find that the only number from the given list that is not divisible by 4 is 2. Since 2 does not fit with the other numbers based on the divisibility rule, we conclude that it is the unique number that does not share the same pattern as 20, 4, 8, and 300.
