Answer:
start with -29, multiply each term by 3
start with 90, multiply each term by 0.2
start with 67 and multiply each term by 2
The colony has 8576 cells after 7 minutes
Step-by-step explanation:
The pattern for the first part of Q2 is multiply each term by 3.
-29, -87, -261, -783... start with -29, multiply each term by 3
The pattern for the second part of Q2 is multiply each term by 0.2.
90, 18, 3.6, 0.72... start with 90, multiply each term by 0.2
The pattern for the third part of Q2 is multiply each term by 2
start with 67 and multiply each term by 2
The colony has 67×2×2×2×2×2×2×2= 8576 cells after 7 minutes
