The figure below shows a shaded region and a nonshaded region. angles in the figure that appear to be right angles are right angles.

there's a rectangle with 2ft 16ft and 8ft. inside of the triangle, the shaded region is 8ft,2ft, 2ft, and 1ft

what is the area, in square feet, of the shaded region?
square feet

what is the area, in square feet, of the nonshaded region?
square feet

50- 250 is correct i did that one too

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

what is the question?
