Step-by-step explanation:

are bhai kaha na kya chate hi

Answer 2

a = -3 (as a is 1st term)

2nd term is -5

I don't know about y as it is not in general notations & you didn't mention what is y here. So, kindly mention.

If you mean y to be last term then,

y = -3+(n-1)(-2)

=>y=-3-2n+2

Then, y is -(2n+1)

Hope it helps!
