Consider the sequence +o { 10T ;} (2n)! By using a ratio of successive test, the sequence is O the ratio is greater than 1 and the sequence is strictly increasing the ratio is less or equal to 1 and the sequence is increasing O the ratio is greater than 1 and the sequence is strictly decreasing the ratio is less than 1 and the sequence is strictly decreasing O the ratio is greater or equal to 1 and the sequence is increasing
