Here's the formula:

where a_1 is the first term in the sequence and d is the common difference.

In the sequence, the first term, a_1 is 11, and it appears that 6 is the common difference (d=6) since 11+6=17, 17+6=23, and so on. So, by plugging in your answers, you get the above answer.

the answer

b. they are parallel and will never intersect.

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
