Answer / Km Neelam Saini

This question involves a recurrence relation that doesn't have an explicit solution. However, we can find the pattern for X > 5 by comparing the difference between f(X) and f(X-1). Given that f(X)-f(X-1)=f(X-8), we can infer that every 8th term after the fifth has a constant difference. So, to find X, we need more information about this constant difference.
