hope it will be helpful to you!!!!

Answer 2

Answer:

This is not an AP

Step-by-step explanation:

It is a GP of a=-2 and r or product difference =-1

for it to be an AP it should satisfy

b=(a+c)/2

$b = (a + c) \div 2$

where then a, b, c are in AP

For GP it should satisfy

$b \: = \sqrt{ac}$

Hope you got it......
