What is the 6th term of the geometric sequence 4, −20, 100, ...?

shtirl [24]

Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500

Answer:

1 pounds of apples $=$ $\$ 1·25

1 pounds of cheese $=$ $\$ 7

1 pounds of coffee beans $=$ $\$ 5·5

1 pounds of fudge $=$ $\$ 9

1 pounds of pumpkin $=$ $\$ 0·88

Step-by-step explanation:

Unit Rate is the ratio between two different quantities with different units

The ratio of cost per items is

$=$ $\frac{dollars}{pounds}$

4 pounds of apples $= \$ 5

4 pounds $= \$ 5

Divided 4 both the side

1 pounds of apples $=$ $\$ 1·25

$\frac{1}{2}$ pounds of cheese $= \$ 3·50

$\frac{1}{2}$ pounds $= \$ 3·50

Divided $\frac{1}{2}$ both the side

1 pounds of cheese $=$ $\$ 7

$\frac{3}{2}$ pounds of coffe beans $= \$ 8·25

$\frac{3}{2}$ pounds $= \$ 8·25

Divided $\frac{3}{2}$ both the side

1 pounds of coffee beans $=$ $\$ 5·5

$\frac{3}{4}$ pounds of fudge $= \$ 6·75

$\frac{3}{4}$ pounds $= \$ 6·75

Divided $\frac{3}{4}$ both the side

1 pounds of fudge $=$ $\$ 9

$\frac{25}{4}$ pounds of pumpkin is $= \$ 5·50

$\frac{25}{4}$ pounds $= \$ 5·50

Divided $\frac{25}{4}$ both the side

1 pounds of pumpkin $=$ $\$ 0·88
