What is the 25th term of this arithmetic sequence? 3, 9, 15, 21, 27, …

147

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a + (n - 1)d

where a is the first term and d the common difference

here a = 3 and d = 9 - 3 = 15 - 9 = 6, hence

= 3 + (24 × 6) = 3 + 144 = 147

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
