Key Topics to Revise
1
Arithmetic Progressions (AP)
- An AP is a sequence where each term differs from the previous term by a constant value called common difference (d)
- General form: a, a+d, a+2d, a+3d, ... where 'a' is the first term
- The nth term formula: Tn = a + (n-1)d
2
Geometric Progressions (GP)
- A GP is a sequence where each term is obtained by multiplying the previous term by a constant ratio 'r'
- General form: a, ar, ar², ar³, ... where 'a' is first term and 'r' is common ratio
- The nth term formula: Tn = ar^(n-1)
3
Harmonic Progressions (HP)
- Numbers are in HP if their reciprocals form an AP
- No direct formula for nth term or sum of HP
- Convert to AP by taking reciprocals, solve, then convert back
4
Advanced Concepts and Applications
- Special cases in AP: when sum of m terms equals sum of n terms
- Different types of GP based on first term sign and ratio value
- Series with continuously decreasing terms and infinite sums
