You can put this solution on YOUR website! How do I find the general term of the arithmetic
sequence a19 = 150, d=9, without the first term?
Solve for the first term:
Substitute n=19, d=9
Substitute 150 for a9
Subtract 162 from both sides
So the nth term is
Substitute a1=-12 and d=9
<-- the general term
