Key Topics to Revise
1
Basic Concepts - Sequences and Series
- A sequence is a function from natural numbers to real numbers, denoted as {a₁, a₂, a₃, ...}
- A series is the sum of terms of a sequence: a₁ + a₂ + a₃ + ...
- Finite sequences have limited terms, infinite sequences continue indefinitely
2
Arithmetic Progression (A.P.)
- Each term is obtained by adding a fixed number (common difference) to the previous term
- General form: a, a+d, a+2d, a+3d, ... where 'a' is first term, 'd' is common difference
- Can have positive, negative, or zero common difference
3
Geometric Progression (G.P.)
- Each term is obtained by multiplying the previous term by a fixed non-zero number (common ratio)
- General form: a, ar, ar², ar³, ... where 'a' is first term, 'r' is common ratio
- Common ratio can be positive, negative, or fraction (but not zero)
4
Relationship Between A.M. and G.M.
- For two positive numbers a and b: A.M. ≥ G.M.
- Equality holds when a = b
- A.M. - G.M. = (√a - √b)²/2 ≥ 0
