We already given first term -3.
Let us find second term 
.
Plugging n=2.
Now taking n=3.
.
Now, n=4.
.
We got terms -3, 2, 7 and 12.
<h3>Therefore, correct option is B) –3, 2, 7, 12.</h3>
This problem can
be directly solved by ratio and proportion.
We know that there
are 646,449 people for every 68.3 square miles, so:
646,449 people : 68.3
square miles = X : 570,374 square miles
We know that the :
symbol signifies division therefore,
646,449 / 68.3 = X
/ 570,374
X = 5,398,502,224
people
