A sequence is generated by a^n =-4(3^n)-1 what is the fifth term ? A.-61
B. -973
C-971
D.728

Step-by-step explanation:

I think what you meant was

an = -4(3^n) - 1

so, this is not meant to be a^n ...

and so when looking for the 5th term it just means n = 5.

a5 = -4×3⁵ - 1 = -4×243 -1 = -972 - 1 = -973

so, B is correct.

a

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|

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
