A sequence of numbers or letters that follow a definite pattern is given. Each question has a blank space. This has to be filled by the correct answer from the four given options to complete the sequence. without breaking the pattern.
5, 10, 30, 150, 1050, --------
$$1\frac{8}{9}, 2\frac{2}{9}, 2\frac{5}{9}, --------, 3\frac{2}{9}$$
(2, 5, 9), (6, 8, 7), (10, 11, 5), -------
$$\frac{1}{2}, \frac{8}{5}, \frac{27}{10}, \frac{64}{17}, -------, \frac{216}{37}$$
The value of the $$13^{th}$$ term in the sequence
1, 3, 6, 10, 15, ......... is
24, 35, 48, 63, -----, 99, 120
