@funscience will you help me?

Answer 4

so we start with -4
-4(-6) is 24

now the sequence is -4, 24

then we multiply 24 by -6 and get -144

now the sequence is -4, 24, -144

then we multiply -144 by -6 and get _______.

now the sequence is -4, 24, -144, ________

then we multiply ________ by -6 and it's the next number in the sequence

keep going until you have six number total and then add all six numbers together.
