Is this arithmetic or geometric ?
\( {4n^2} \)
Not sure how to approach this one. Do I \(4(n1)^2 \)

Best ResponseYou've already chosen the best response.0How do I check? Do I just 4*1^2 =16 4*2^2 = 64 and then check the for the difference and ratio ?

Best ResponseYou've already chosen the best response.0you can do 3 consecutive terms to check. \[a_1=4(1)^2=4\] \[a_2=4(2)^2=16\] \[a_3=4(3)^2=36\] If \(\frac{ a_2 }{ a_1 }=\frac{ a_3 }{ a_2 }\) then it's geometric. If \(a_3a_2=a_2a_1\), then it's arithmetic

Best ResponseYou've already chosen the best response.0Neither of those is true so the sequence is neither arithmetic or geometric

Best ResponseYou've already chosen the best response.0Ok, that is what I was thinking. Thank you and I messed up on my on my powers. I was thinking (4*1)^2 for some reason but it is the way you have it.

Best ResponseYou've already chosen the best response.0no problem. the geometric sequences will look like exponential functions and arithmetic sequences look like linear functions. If it's a higher order polynomial or some other type of function it's neither.
