Thank you...

Answer 1

Woah, Dunno what happened there sorry

Answer 2

So you've got a series here. And you've got to figure out what common situation you've got between successive terms.

Answer 3

There are a few ways to figure that out. For series there are 2 main routes you can take: 1) successive differences and 2) a common ratio.

For Successive Differences you would subtract the previous term by the one after it, and try and find a common difference.

For a Common Ratio, you would divide the succesive term by the previous one, and see if the ratio is the same.

Try these both now on this problem
