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.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
