What is the ninth term in the following sequence 11, 17, 23, 29,.. a 47 b53c 59d65

The given sequence is an arithmetic sequence with a common difference of 6 (as each term is obtained by adding 6 to the previous term).

To find the ninth term, we can use the formula:

nth term = a + (n-1)d

where a is the first term, d is the common difference, and n is the term number we want to find.

Plugging in the given values, we get:

9th term = 11 + (9-1)6

= 11 + 48

= 59

Therefore, the ninth term in the sequence 11, 17, 23, 29,.. is 59. Answer: c 59.
