Thank you We sneak already told us you wanted to

00:04

solve a shmoop the problem So tweet tweet all right

00:08

in a sequence each number is five less than the

00:11

square of the previous number If the first number is

00:14

two what is the fourth number sequence thing All right

00:20

we're told that we're dealing with a sequence and we

00:22

know the pattern Each number is five less than the

00:25

square of the previous number So let's start with the

00:28

first number to find the second term We have to

00:31

square two which gives us for and then take five

00:34

less than that So four minus five is negative One

00:37

is the second term right Third again we square negative

00:41

one which is one Then we subtract five and it

00:44

gives us negative four All right fourth term is what

00:46

we're looking for Negative four squared gives us sixteen then

00:51

subtract five and we get eleven So fourth number is 00:00:54.499 --> [endTime] eleven and we've got our answer
