Arithmetic And Geometric Series
Bayani Gaba-gaba
Sequences appear everywhere: in savings accounts earning compound interest, in the spacing of fence posts, in the decay of radioactive atoms. Recognising whether a sequence is arithmetic or geometric unlocks powerful formulas that let you jump straight to the 100th term or add a thousand terms in a single calculation, without writing them all out.
This topic equips you with the general-term and summation formulas for both types of series. You will learn to handle finite sums, discover when an infinite geometric series converges, and master the techniques examiners reward in the 4PM1 papers. Every formula is derived so you understand where it comes from, not just how to use it.
Manufura
- Know the general term of an arithmetic series
- Use the sum to n terms of an arithmetic series
- Know the general term of a geometric series
- Use the sum to n terms of a finite geometric series
- Use the sum to infinity of a convergent geometric series, including the use of |r| < 1
