Given the first term and the common ratio of a geometric sequence find the explicit formula.

lisov135 [29]

A geometric sequence is generated by multiplying the first term in the sequence, $a_1$ , several times by a fixed scalar $r$ . So

$a_2=a_1r$

$a_3=a_2r=a_1r^2$

$a_4=a_3r=a_1r^3$

and so on, down to

$a_n=a_{n-1}r=a_{n-2}r^2=\cdots=a_1r^{n-1}$

Using the result above, the sequences you're interested in are

31) $a_n=-(-2)^{n-1}$

33) $a_n=4(-4)^{n-1}$

We can rewrite these results to make them slightly cleaner.

$-(-2)^{n-1}=-(-1)^{n-1}2^{n-1}=(-1)^n2^{n-1}$

$4(-4)^{n-1}=4(-1)^{n-1}4^{n-1}=(-1)^{n-1}4^n$

If cot theta = 3/2, what is the value of csc theta?

Arturiano [62]

The value of csc theta is $\frac{3. 61}{2}$

<h3>How to determine the value</h3>

It is important to note that the ratio for cot is given as;

Cot theta = adjacent/opposite

cosec theta = hypotenuse/opposite

If cot theta = 3/2, then

Adjacent = 3

Opposite = 2

Using Pythagoras theorem, we have

Hypotenuse square = opposite + adjacent square

$H = \sqrt{2^2 + 3^2}$

$H = \sqrt{4 + 9}$

$H = 3. 61$

Cosec theta = $\frac{3. 61}{2}$

Thus, the value of csc theta is $\frac{3. 61}{2}$
