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... <u>start with -29, multiply each term by 3
</u>
The pattern for the second part of Q2 is multiply each term by 0.2.
90, 18, 3.6, 0.72... <u>start with 90, multiply each term by 0.2
</u>
The pattern for the third part of Q2 is multiply each term by 2
<u>start with 67 and multiply each term by 2
</u>
The colony has 67×2×2×2×2×2×2×2= <u>8576 cells after 7 minutes</u>
