Which of the following are geometric series?

Temka [501]

Answer:

-256 +64 - 16 + 4 - 1

Step-by-step explanation:

A series is the summation of all the terms in a sequence.

So it is only the last three options that qualify to be a series.

The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.

The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.

The series -256 +64 - 16 + 4 - 1 has a common ratio of

$r=\frac{64}{-256}=-\frac{1}{4}$

There the only series that is geometric is.

-256 +64 - 16 + 4 - 1

attashe74 [19]

13) Answer: $-3a^3b^2$

$\left(-6a^2b\right)\left(\frac{1}{2}ab\right)$

$=-6a^2b\frac{1}{2}ab$

$=-6a^2b^2\frac{1}{2}a$

$=-6a^3b^2\frac{1}{2}$

$=-3a^3b^2$

14) Answer: $8y^5x$

$12y\left(\frac{2}{3}xy^4\right)$

$=12\cdot \frac{2}{3}xy^{1+4}$

$=12\cdot \frac{2}{3}xy^5$

$=\frac{2\cdot \:12xy^5}{3}$

$=\frac{24y^5x}{3}$

$=8y^5x$
