Answer:

3/2

Step-by-step explanation:

Basically just multiply 1/2 by numbers.

1/2 * 2 = 1

1/2 * 3 = 3/2

1/2 * 4 = 2

1/2 * 5 = 5/2

And so on.

Answer:

$T_{2} = 200$

Step-by-step explanation:

Given

Geometry Progression

$T_1 = 500$

$T_4 = 32$

Required

Calculate the second term

First, we need to write out the formula to calculate the nth term of a GP

$T_n = ar^{n-1}$

For first term: Tn = 500 and n = 1

$500 = ar^{1-1}$

$500 = ar^{0}$

$500 = a$

$a = 500$

For fought term: Tn = 32 and n = 4

$32 = ar^{4-1}$

$32 = ar^3$

Substitute 500 for a

$32 = 500 * r^3$

Make r^3 the subject

$r^3 = \frac{32}{500}$

$r^3 = 0.064$

Take cube roots

$\sqrt[3]{r^3} = \sqrt[3]{0.064}$

$r = \sqrt[3]{0.064}$

$r = 0.4$

Using: $T_n = ar^{n-1}$

$n = 2$ $r = 0.4$ and $a = 500$

$T_{2} = 500 * 0.4^{2-1}$

$T_{2} = 500 * 0.4^1$

$T_{2} = 500 * 0.4$

$T_{2} = 200$

<em>Hence, the second term is 200</em>

Fiesta28 [93]

Answer:

$x = 7$

Step-by-step explanation:

Given

$\frac{4}{3}x - \frac{1}{3} = 9$

Required

Solve for x

$\frac{4}{3}x - \frac{1}{3} = 9$

Add $\frac{1}{3}$ to both sides

$\frac{4}{3}x - \frac{1}{3} + \frac{1}{3} = 9 + \frac{1}{3}$

$\frac{4}{3}x = 9 + \frac{1}{3}$

Take LCM

$\frac{4}{3}x = \frac{27 + 1}{3}$

$\frac{4}{3}x = \frac{28}{3}$

Multiply both sides by $\frac{3}{4}$

$\frac{3}{4} * \frac{4}{3}x = \frac{3}{4} *\frac{28}{3}$

Evaluate the left hand side

$x = \frac{3}{4} *\frac{28}{3}$

$x = \frac{28}{4}$

Divide 28 by 4

$x = 7$
