How to Solve Geometric Progression Problems
A geometric progression (GP) is a sequence where each term is the previous term multiplied by a fixed common ratio r, so the nth term is a×r^(n-1) and the sum…
How to Solve Arithmetic Progression Problems
An arithmetic progression (AP) is a sequence where each term is the previous term plus a fixed common difference d, so the nth term is a + (n−1)d and the sum o…
How to Solve Harmonic Progression Problems
A harmonic progression (HP) is a sequence whose reciprocals form an arithmetic progression, so the standard technique is to invert every term, solve the result…
How to Solve Sum of Series Problems
Sum-of-series problems are solved by first classifying the pattern — arithmetic, geometric, or a special standard series like squares or cubes — then applying…
How to Solve Arithmetico-Geometric Series Problems
An arithmetico-geometric (AGP) series has each term formed by multiplying the corresponding terms of an AP and a GP — like 1, 3x, 5x², 7x³ — and its sum is fou…
