Explanation

Given:  

15 workers complete the work in 20 days  

Step 1: Find total work  

Total work = Number of workers x Number of days  

Total work = 15 x 20 = 300  

Step 2: Find workers needed for 10 days  

Let the required number of workers = W  

W x 10 = 300  

W = 300 / 10  

W = 30

30 → 18 (−12)

18 → 15 (−3)

15 → 7 (−8)

7 → 4 (−3)

The subtraction alternates with a larger number and −3:

−12, −3, −8, −3

So, the next number is:

7 − 3 = 4
