Write the explicit formula for the geometric sequence.
a1 = 5 a2 = 20 a3 = 80
A. an = 5 • (4)n
B. an = 5(4)n1
C. an = 4(5)n1
D. an = 5 • (4)n

Best ResponseYou've already chosen the best response.2It would be B because in a geometric sequence, you have \[\large ar ^{n1}\] and in finding our r, we take \(\large\frac{ a _{2} }{ a _{1} }\) and that is 4

Best ResponseYou've already chosen the best response.1This way you can eliminate A because term 2 doesn't match up... And I think Jhanny's right

Best ResponseYou've already chosen the best response.2So we have a1 = 5, our r = 4 and plug it into our formula \[\large ar ^{n1}\]

Best ResponseYou've already chosen the best response.2Alright, for this one you have a variable with two different powers dividing eachother, and in this case, we can simply do this. \[\large \frac{ 1 }{ q ^{\color{red}{(33/4)8} }}\]

Best ResponseYou've already chosen the best response.2\[\frac{ 33 }{ 4 }8*(\frac{ \color{green}{4} }{ \color{green}{4} })= \frac{ 33 }{ 4 }\frac{ \color{darkorchid}{32} }{ \color{darkorchid}{4} }\]

Best ResponseYou've already chosen the best response.2solve (33/4)(32/4) and we'll work from there, you'; get your answer, promise :)

Best ResponseYou've already chosen the best response.2\[\large (3x ^{\color{forestgreen}{7/2}})^{\color{blue}{6}}(x ^{\color{green}{2}})^{\color{blue}{6}}\] here, we will start 1 part at a time. lets start with \(\large (3x ^{7/2})^{6}\)

Best ResponseYou've already chosen the best response.2Hm.. not exactly, we have \[\large(3^{\color{blue}{6}})(x ^{\color{blue}{(7/2)(6)}})\] which gives us \[\large(729x ^{21})\]

Best ResponseYou've already chosen the best response.2Now that we've taken care of the first part, we can move onto the second part, which is \[\large (x ^{2})^{6} = x ^{\color{red}{6*2}}= x ^{\color{blue}{12}}\]

Jhannybean

Best ResponseYou've already chosen the best response.2Now we can combine both parts together so we get \[\large (729x {^\color{green}{21}}) *(x ^{\color{green}{12}}) = 729x ^{\color{red}{21+12}}\]

Best ResponseYou've already chosen the best response.2And adding 21 + 12 for the exponent, you'll get your answer. i've done the rest
