The third one, 40-45 because the difference of the rest are 4, while that one is 5.
Plug in n = 1 into the nth term formula
a(n) = 4n-1
a(1) = 4*1-1
a(1) = 3
So the first term is 3
The second term will be 7 because we add on 4 each time, as indicated by the slope of 4. This is also known as the common difference.
So the nth term is found by adding 4 to the (n-1)st term, in other words,
a(n) = a(n-1)+4
----------------------------------------------------------------------------
In summary, the answer is
a1=3; an=an-1+4
which is choice B
15% = 15/100 = 0,15
36000•0,15=5400
Parallel lines are in the same plane, never intersect, and have the same slope.
The polygon would have 18 sides. Hope this helps!
