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.

Yes

Step-by-step 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.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
