Hello :
<span>the nth term of a geometric sequence is :
Un = Up ×r^(n-p) . r is the common ratio
for : p=5 and n= 2
U5 = U2 ×r^3
16 = -2 r^3
r^3 = -8
but : -8 = (-2)^3
so : r = -2
Un = U2 × r^(n-2)
Un = -2 ×(-2)^(n-2)= (-2)^(n-2+1)
</span><span>the nth term of a geometric sequenceis : Un = (-2)^(n-1)</span>
It would be $0.50. Each Heads earns you $0.50 and if you pay $0.50 you have a chance of doubling your money.
Answer:
400
Step-by-step explanation:
8% of 5000 is 400. Math:
5000 x 0.08 = 400
7b / 12 = 4.2
multiply both sides by 12
7b = 50.4
divide both sides by 7 to isolate b
b = 7.2
