Find the next three terms of the following arithmetic sequence -2, -5, -8, -11,

Mariulka [41]

Answer: -14, -17, and -20

Step-by-step explanation: Study the sequence.

Notice that each number is 3 less than the number before it.

In other words, -2 - 3 is -5, -5 - 3 is -8, and -8 - 3 is -11.

Now, if we continue with this same sequence,

-11 - 3 is -14, -14 - 3 is -17, and -17 - 3 is -20.

So the next three numbers are -14, -17, and -20.

To visualize better, look at it like this:

$\frac{3r^3}{2r}$

First, see if you can simplify 3/2. You can't, so leave it like that.

The rule for exponents is you subtract the exponent from the bottom (r) from the exponent on the top ( $r^3$ )

$r^3 - r^1 = r^2$

Put that on the top, and you get

$\frac{3r^2}{2}$
