$\stackrel\star{\rightsquigarrow\circ\boldsymbol{\underbrace{Answer}\circ\leftharpoonup}}$

1. This sequence is arithmetic

2. The common ratio is 3.

$\stackrel\star{\rightsquigarrow\circ\boldsymbol{\underbrace{Explanation.}}}\circ\leftharpoonup$

$\bullet$ Difference between arithmetic and geometric sequences

$\twoheadrightarrow\sf Arithmetic\quad sequences$ - In arithmetic sequences, we add the same amount to obtain the next term.

$\twoheadrightarrow\sf Geometric\quad sequences$ - In geometric sequences we multiply times the same amount to obtain the next term.

$\bullet$ Since we add the same amount to get the next term, the given sequence is arithmetic

$\twoheadrightarrow\sf Common\;difference:-3$

$\bullet$ In the given sequence we add -3, or subtract 3, to obtain the next term

Answer 2

Answer:

It is arithmetic progression

Step-by-step explanation:

If wwe see, the numbers are going down by 3 each time, therfore the common difference is 3
