20 Solved AP GP Formula Questions for CAT 2026 Practice
A CAT 2026 practice set of 20 AP GP formula questions structured into 4 clusters of 5 with step-by-step solutions: AP basics (nth term, sum forms, AM, sum of n), GP fundamentals (nth term, finite + infinite sum, GM, repeating decimal), AGP and special series (sum of squares, cubes, odd squares), and HP with the AM-GM-HM family. Designed to be re-run three times across the prep cycle: untimed accuracy, timed speed, mixed-order recognition.

AP GP Formulas vs HP Formulas: Tricks for CAT 2026
A side-by-side comparison of arithmetic, geometric, and harmonic progressions for CAT 2026. Covers definitions, sum formulas (AP and GP have closed forms; HP does not), the AM-GM-HM bridge identities, CAT 2018-2025 recurrence counts (GP 8/8 years, AP 7/8 years, HP 4/8 via HM only), and the verdict that progression-revision time should mirror actual CAT recurrence. Plus 3 mistakes (HP closed-form sums, AM-HM swap, mid-question switch) and 6 lessons.

6 AP GP Formula Shortcuts to Solve CAT in 60 Seconds
A speed-math drill for CAT 2026 AP GP questions, built around 6 shortcuts that crack the topic in under 60 seconds: infinite GP for repeating decimals, AP Gauss for first-and-last visible, AM-GM equality lock for max-product, HM for equal-distance average speed, AP back-calc from sum, and sum-of-squares with parity adjustment. Each shortcut comes with a timed worked example, a recognition tag, and the 10s tag - 30s apply - 20s verify budget breakdown.

AP GP Important Formulas: CAT 2018-2025 Pattern Map
A CAT 2018-2025 8-year pattern analysis of which AP GP formulas keep getting tested. Covers the 6 high-recurrence formulas (infinite GP every year, AP sum 7 of 8, AP nth term 6 of 8, AM-GM 5 of 8, GM 5 of 8, HM 4 of 8), year-by-year question reconstruction, 3 repeating disguise types (bouncing ball, equal-distance speed, compound deposit), and a 4-week revision protocol that mirrors actual CAT recurrence.
