Nnesha:

Given first term and common ratio(so it's geometric sequence ) \[a_n=a_1(r)^{n-1}\] common ratio represent that next term is 4 times bigger than the previous one if first term is 2 then next term is 4 times 2 you can plug in the values for first term and common ratio and graph the equation

Vocaloid:

none of the graphs look right to me, but the graph where x = 1 and y = 2 is "closest" to the given data

Nnesha:

\[\large\rm \color{Red}{a_1=2 } ~~~~~\color{blue}{r=4 } \]\[a_n =\color{red}{a_1}(\color{blue}{r})^{n-1}\]

Nnesha:

yeah all of them are concave down but the term is positive

Vocaloid:

the model seems logarithmic to me

ThatCreepyBoy:

Oh okie :O Thank you both
