You just substitute in the values: a3 = a(n+2) = a(1+2) = (a1+1)/a(1) = a2/a1 = -2/3. Now you have a3. Calculate a4. Then keep going.

You probably want to double-check these, it's getting late.....$$a_1=3,~ a_2=-2 \implies a_3=-2/3\implies a_4=1/3\implies a_5=-1/2$$

Thanks guys! But alas, I see how a3 is found. a4 and a5 allude me.

anonymous · Answer

$$a_4=\frac{a_3}{a_2}$$

anonymous · Answer

$$a_5=\frac{a_4}{a_3}$$
