Overview
Progressions is a fundamental chapter in mathematics that deals with sequences of numbers following specific patterns. This chapter explores two main types of progressions: Arithmetic Progressions (A.P.) where terms increase or decrease by a constant difference, and Geometric Progressions (G.P.) whe
Key Concepts
A sequence where each term after
A sequence where each term after the first is obtained by adding a fixed number (common difference 'd') to the preceding term. General form: a, a+d, a
The constant value added to each
The constant value added to each term to get the next term in an A.P. It can be positive, negative, or zero. Found by subtracting any term from the su
Two formulas
Two formulas: Sn = n/2[2a + (n-1)d] when first term and common difference are known, or Sn = n/2(a + l) when first and last terms are known, where l i
A sequence where each term after
A sequence where each term after the first is obtained by multiplying the preceding term by a fixed non-zero number called common ratio 'r'. General f
The constant factor by which each
The constant factor by which each term is multiplied to get the next term in G.P. Found by dividing any term by the preceding term: r = ak+1/ak where
