Answer:
k = 4.
Step-by-step explanation:
An arithmetic sequence has a common difference.
So for this to be arithmetic:
k + 3 - (k - 1) = 3k - 1 - (k + 3)
k + 3 - k + 1 = 3k - 1 - k - 3
3 + 1 = 2k - 4
4 + 4 = 2k
k = 4.
The sequence is 3, 7, 11.

Answer:
24 square units
Step-by-step explanation:
The triangle is a right triangle with legs 6 and 8. Its area is ...
A = 1/2bh = 1/2(6)(8) = 24 . . . . square units
_____
<em>Additional comment</em>
The equation for a line in <em>intercept form</em> is ...
x/a + y/b = 1
where 'a' and 'b' are the x- and y-intercepts, respectively. If we divide the given equation by 2, we get ...
x/6 +y/8 = 1
showing us that the x- and y-intercepts are 6 and 8. This is also clear on the graph.
