Answer:
134
Step-by-step explanation:
This sequence is arithmetic because it's going up by sane number, 3. Hence, it also linear for the same reason. The equation is y=3x+(0th term). The 0th term is the one before the 1st term, 11, which would be 8.
So the equation to finc any xth term is y=3x+8.
Example, first term is 3(1)+8=11.
Example, second term is 3(2)+8=14.
Example, third term is 3(3)+8=17.
The 42nd term is 3(42)+8=126+8=134.

Because the window is 4 feet and you need it to cover the window and the floor, you could start with the window. 4 feet at 12 inches per foot is 48 inches already. Then you would add the distance between the window and the floor, 21/2 feet is 10.5 feet. 10.5 * 12 inches is 126 inches. 126+48=174. You need 174 inches. See my pic
