Can someone give me the answers and step by step instructions please??

 neither

 geometric progression

 arithmetic progression

Step-by-step explanation:

Given:

sequences:

To find: which of the given sequence forms arithmetic progression, geometric progression or neither of them

Solution:

A sequence forms an arithmetic progression if difference between terms remain same.

A sequence forms a geometric progression if ratio of the consecutive terms is same.

For :

Hence,the given sequence does not form an arithmetic progression.

Hence,the given sequence does not form a geometric progression.

So, is neither an arithmetic progression nor a geometric progression.

For   :

As ratio of the consecutive terms is same, the sequence forms a geometric progression.

For :

As the difference between the consecutive terms is the same, the sequence forms an arithmetic progression.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
