Arithmetic And Geometric Progression
  1. Arithmetic Progression (AP)
    1. a - First term
      1. d - Common difference
        1. Tn - nth term of AP
          1. Tn = a + (n-1)d
            1. Sn = (n/2) (2a + {n-1}d)
              1. Sn = (n/2) (a + Tn)
                1. Sn = (n/2) (a + l)
                2. l = Last term of Ap
                3. Geometric Progression (GP)
                  1. a = First term
                    1. r = ratio
                      1. Tn = a * r^(n-1)
