    Topic: Arithmetic Progression, with some twist

    Formula: An = A₁  + (n-1) d

                    An = nth term

                     A₁ = first term

                      n = terms

                     d = difference

    Notice that the sign chances every 1 step.

    for odd term, sign is positive (+)

    for even term, sign is negative (-)

    An=2n+1

    An=a1(n-1) d

    An=3(n-1) 2

    An=3+2n-2

    An=2n+1
