What is the recursive rule for this geometric sequence? 12,−2,8,−32,... a1=1/2;an=−4⋅an−1
a1=−4;an=1/2⋅an−1 a1=−1/2;an=4⋅an−1 a1=1/2;an=2⋅an−1
2 answers:
a1=12;an=−4⋅an−1 would be the answer
A=1=-4;an=1/2.an-1 or it might be a1=1/2;an=4.an-1

42 firefighters in total.
16 volunteered for the special rescue team.
n + 16 = 42
or it could be this way:
42 - 16 = n
You would do 300• 31/100 to get 90. I’m pretty sure that’s right
17/10-(2/5x2/2)
17/10-4/10
=13/10
For company a it would be at the 8th hour and they would be 210 and for company b it would be at the 7th hour
