Final answer:
The sequence follows a pattern of multiplying by -3. Continuing this, the next two terms in the pattern are 1215 and -3645.
Step-by-step explanation:
The pattern shown in the sequence is a multiplication by -3 for each subsequent number. To continue the pattern, multiply the last number by -3 again.
Starting with -5 and multiplying by -3, the result is 15.
Multiply 15 by -3 to get -45.
Continue in this fashion to get 135, then -405.
For the next term, multiply -405 by -3, which equals 1215.
The following number is obtained by multiplying 1215 by -3, which gives -3645.
Therefore, the next numbers in the pattern are 1215 and -3645.
