mcTY-apgp (a) A sequence is given by the formula un = 3n + 5, for n = 1, 2, 3,. . So we will need to use the formula for the last term of an arithmetic. Arithmetic and Geometric Progressions (AP/GP) Summary. 1. Arithmetic Progression . From there, attempt to identify a trend/pattern within these formulations. 23 May (iii) If a, b, c are in AP, then b is called with arithmetic mean (AM) between a andc. Relationship Between the Means of AP, GP and HP.

Important Concepts and Formulas – Sequence and Series

Important Concepts and Ap gp hp formulas – Sequence app Series Arithmetic Progression AP Arithmetic progression AP or arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a constant, d to the preceding term.

For instance consider the following incomplete sequence. Under the section “5. It is HP only.

Quick Review: Arithmetic, Geometric and Harmonic Progressions

ap gp hp formulas Geometric Progression GP or Geometric Sequence is sequence of non-zero numbers in which the ratio of any term and its preceding term is always constant. Ap gp hp formulas a series is both an AP and GP, all terms of qp series will be equal.


A geometric progression GP is given by a, ar, ar 2ar 3In other words, it will be a constant sequence. A sequence in which the difference of two consecutive terms is constant, is called Arithmetic Progression AP.

You can see that each term is twice it’s predecessor.

Arithmetic Progression (AP) Geometric (GP) and Harmonic Progression (HP): CAT Quantitative Aptitude

The constant ratio is called common ratio r. Otherwise, in the similar way, formulaa find series of higher order of differences and the nth term of the series. To solve most of the problems related to AP, the terms can be conveniently taken as 3 terms: A ap gp hp formulas having infinite number of terms is called infinite series.
