Quizplus · Accepted Answer

The sequence is an arithmetic sequence with a common difference of 2 (each term increases by 2). The first term is 5. To find the fifth term (a), we add the common difference 4 times to the first term: 5 + 2*4 = 5 + 8 = 13. However, there seems to be a mistake in my calculation based on the provided options. Given the pattern, the correct approach to find the nth term is using the formula for the nth term of an arithmetic sequence: a_n = a_1 + (n-1)d, where a_1 is the first term, n is the term number, and d is the common difference. For the 5th term: a_5 = 5 + (5-1)*2 = 5 + 8 = 13. It appears there was an error in the initial explanation regarding the options provided. The correct calculation for the 5th term indeed results in 13, which is not listed among the options, suggesting a misunderstanding in the question's context or a mistake in the provided options.
