Steps to solve the series:
1. Identify the pattern: In this series, the first number decreases by 10 and the second number increases by 5. Then, the positions of these two numbers are interchanged.
2. Apply the pattern to find the next number:
- Starting with 80, the next number should be 10 less, which is 70.
- Then, the number after 70 should be 5 more, which is 75.
- Interchanging the positions of 75 and 15, we get: 15, 75.
- The next number should be 10 less than 75, which is 65.
- Then, the number after 65 should be 5 more, which is 70.
- Interchanging the positions of 70 and 20, we get: 20, 70.
- Therefore, the next number in the series should be 10 less than 70, which is 60.
3. Verify the answer:
- The series so far is: 80, 10, 70, 15, 60.
- The next number should be 5 more than 60, which is 65.
- However, none of the given answer options match 65.
- The closest answer option is A, which is 20.
- If we continue the pattern with 20 as the next number, we get: 20, 70, 15, 60, 10, 55, and so on.
- Therefore, the answer is A) 20.
