URGENT! Please I need help on geometric sequences!

= multiply

1.Generate the next three terms of each geometric sequence defined below.

a)a₁ - 8 with r= -1

b) a_n = a_n-1 3/2 and a₁ = 16

c) t_n+1 = t_n -2 and t₁ = 5

2.Given that a₁ = 5 and a₂ = 15 are the first two terms of the geometric sequence, determine the values of a₃ and a_10. show your calculations.

3.If the complex geometric sequence is defined by c₁ = -7 + 4i and r = i, where i = sqrt-1, then which of the following values is the value of c_5.

a) 7 - 4i

b) 4 - 7i

c) -7 + 4i

d) -4 + 7i

4.a geometric sequence, it is known that a₁= 1 and a₄= 64 . The value of a₁₀ is

a) -65,536

b)262,144

c)512

d) -4096

Determine If arithmetic or geometric then solve:

5. What would result in more money on the 31st day of the month: (1) Getting paid $100 on the first day and an extra $100 per day thereafter or (2) Getting paid 1 penny on the first day and having that amount double each day thereafter? Show calculations for both schemes to justify your answer.
