The general term is obtained by starting with the initial value 5 and then subtracting 4 each time you wish to generate a new term:
a2 = second term = 5+(2-1)(-4) = 5+(-4) = 1
General term:
an = nth term = 5+(n-1)(-4)
Thus, the 21st term is 5+(21-1)(-4) = 5 + (20)(-4) = -75 (answer)

Answer:
B) 161.5 in²
Step-by-step explanation:
We can separate the kite figure into <em>two triangles, by cutting it vertically</em>.
So, we have two triangles with the area of <em>1/2*(6+13)*8.5</em>.
Since there is <em>two</em> of them, the equation of the total area is <em>2*1/2*(6+13)*8.5</em>.
Simplify: <em>1*19*8.5</em> (2 and 1/2 cancel out).
Multiply: <em>19*8.5</em> = 161.5 in²
Okay what problem is it that you need help with??
Answer:
-4/2 is equal to -2.
-2 times -4 is equal to 8.
Therefore, (-4)-4/2
