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
