Is This Actually a Radius of Convergence Problem? 🤔 IIT JAM Mathematics 2026

In this video, we tackle a challenging Real Analysis question (Q12) regarding the interval of convergence for a non-standard infinite series involving variable rational terms. We break down why treating this strictly as a standard power series leads to common calculation mistakes, and how to correctly implement the Cauchy Root Test alongside absolute inequalities to isolate the bounds of the open interval $(a, b)$.This concept-clearing masterclass covers essential Infinite Series convergence tests, properties of sequences of real numbers, absolute value inequalities, and limit behavior crucial for ranking high in the IIT JAM Mathematics 2026 exam. Whether you are actively working through IIT JAM Previous Year Questions or getting an early start on your long-term IIT JAM 2027 Preparation, this video will provide you with elite problem-solving speed and exact logical execution.

DK MathPrep – Vision & Mission:
The vision and mission of DK MathPrep is to help students from Tamil Nadu secure admission to top-tier institutes such as IIT, ISI, CMI, IISER, TIFR, and IISc. We aim to provide the right guidance, quality coaching, and awareness required for students to achieve their academic goals and pursue excellence in mathematics and science.

Founder of DK MathPrep:
Deepak S is an M.Sc. Mathematics student at IIT Madras. While preparing for IIT JAM and ISI entrance examinations, he realized that there was very little quality content available in both Tamil and English for these exams on YouTube. DK MathPrep was created to bridge that gap and ensure that future aspirants have access to the resources, guidance, and mentorship they need to succeed.
