For this question, I am looking at the solution and I’m just not sure how you get to 5(k−1) +1 and 5(k+1)−1 for the range.
Any help would be appreciated.
Try with an easy example first.
What would be an easy example?
- Can there be 16 workers in the company?
- What is the smallest possible number of workers in the company? What about the second-smallest?
