Step-by-step explanation:
The general, nth term, of a sequence is given by the formula:
We can plug in n = 1 to find the first term, thus we have:
We can plug in n = 2, to the find the 2nd term, which is:
Similarly, to get 11th term, we simply plug in n = 11 into the general term rule. so we have:

Answer:
This is an example of a combined 45 45 90 triangle and a 60 30 90 triangle. I have put the pictures showing the side lengths.
Step-by-step explanation:
On the 30 60 90, the hypotenuse is 6.
6 = 2x
x = 3
therefore, the two legs of the triangle are measured as 3 and 3
Now that we have 3 as one of the legs for the other triangle, using the picture of the 45 45 90 triangle, the hypotenuse must be x
.
Since x = 3, x
is 3
x
Therefore x=3
