u have to give a photo of the question or something I can go off of to answer
Given that the nth rule for the sequence is
We need to determine the seconds, fourth and eleventh terms of the sequence.
<u>Second term:</u>
The second term of the sequence can be determined by substituting n = 2, in
Thus, we have;
Simplifying, we get;
Thus, the second term of the sequence is 20.
<u>Fourth term:</u>
The fourth term of the sequence can be determined by substituting n = 4 in
Thus, we have;
Simplifying, we get;
Thus, the fourth term of the sequence is 44.
<u>Eleventh term:</u>
The eleventh term of the sequence can be determined by substituting n = 11 in
Thus, we have;
Simplifying, we get;
Thus, the eleventh term of the sequence is 128.

Answer:
PR = 8
Step-by-step explanation:
The median bisects the side opposite the vertex, so ...
P is the midpoint of AC
Since AC = 25, the length of half that segment is PC = 12.5. Of course, that is the sum of segments PR and RC:
PR + RC + PC
PR + 4.5 = 12.5 . . . . . fill in the known values
PR = 8 . . . . . . . . . . . . .subtract 4.5
if the cube's side equals 2 then it would be 2 x 2 x 2 = 8 or you could say 2 to the 3rd power or 2 cubed
