4. geometric c r = 4

do you follow the reasoning

can you finish this off?

6 looks tough

Answer 4

umm yeah I think I get it, so you are subtracting 2 to get each successive term in number 5

Answer 5

6 is a G eometric

Answer 6

but how do u know its geometric?

Answer 7

For 6th one Divide 2nd term by 1st term. You will get c.r = 3/4
