freckles · Answer

-8 is the first term
...and your second term can be found by multiplying 5 to your previous term

freckles · Answer

$$a_n=5 \cdot a_{n-1}  \text{ this says  \to find next term just multiply previous term by 5}$$

anonymous · Answer

so the second term would be -40? because 5 x -8 = -40?

freckles · Answer

$$\text{ replace } n \text{ with 2} \ a_2=5 \cdot a_{2-1} \ a_2=5 \cdot a_1 $$
see you are just multiplying previous term by 5 to find the term
