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>

Answer:
16 tickets
Step-by-step explanation:
Number of tickets he has to sell = 25
Number of tickets he has sold = 9
How many tickets does he still need to sell?
Number of tickets he still needs to sell = Number of tickets he has to sell - Number of tickets he has sold
= 25 - 9
= 16 tickets
Number of tickets he still needs to sell = 16 tickets
Therefore, Fahad still needs to sell 16 more tickets
