this sequence (not correct to call it a series, a series infers a summation) is decreasing.
for a series to be decreasing the next term must be smaller than the current term.show is strictly decreasing.
2n +1 < 2(n +1) + 1 (n^th term and n^th + 1)
2n + 1 < 2n +3
the next term is less than the previous therfor the series is decreasing.
Am I correct?
