Answer:

1. False 2. True

Step-by-step explanation:

For a geometric sequence,

$\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}$

1. The sequence is :

3, 13, 23, 33,...

$\dfrac{13}{3}\ne \dfrac{23}{13}$

It is not geometric. It is false

2. The sequence is :

5, -25, 125, -625

$\dfrac{-25}{5}=\dfrac{125}{-25}\\\\-5=-5$

So, the sequence is geometric as the common ratio is same. It is true.
