Question

Marcus wrote the equation t(n) = 11 + 3n for a sequence that he was thinking about. Is it

possible that 89 is a part of his sequence? Explain.

Answer 1

Answer: Yes

Explanation:

89 will be one of the terms, so put 89 on t(n).

t(n) = 11 + 3n

89 = 11 + 3n

89 - 11 = 3n

78 = 3n

n = 26

From here we can see that 89 is 26th term, so it is possible that 89 is a part of his sequence.
