    Mathematics

    What is sequences (ap & gp)?

    Sequences and series cover arithmetic progressions, geometric progressions and their sums, including infinite geometric series.

    Why it matters

    They generalise pattern work and are examined across Class 11 and entrance papers.

    Key concepts you will practise

    • nth term of an AP and a GP
    • Sum of n terms of an AP and a GP
    • Arithmetic and geometric means
    • Sum of an infinite GP when |r| < 1

    Tips that save marks

    • Identify whether the difference or the ratio is constant before choosing formulas.
    • An infinite GP only converges when the common ratio lies strictly between −1 and 1.

    Frequently asked questions

    What is the difference between AP and GP?

    An AP adds a fixed number each time; a GP multiplies by a fixed number each time.

    What is the sum of an infinite GP?

    a / (1 − r), valid only when the modulus of r is less than 1.
