Which expression represent the nth number in this sequence?

a(n) = 5 + 13(n - 1)

Step-by-step explanation:

Note that each new number is obtained by adding 13 to the previous number.  The common difference is 13 and the first number is 5.  The general formula for an arithmetic sequence is

a(n) = a(1) + d(n - 1), where d is the common difference.

Here,

a(n) = 5 + 13(n - 1)

-232

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|
