Best ResponseYou've already chosen the best response.4Pick \(\large X_o=1 \) , that seems easiest.

Best ResponseYou've already chosen the best response.4The the first three values are \[\Large{ X_o = 1 \\ \\X_1 = (2)^1\cdot X_0= 2 \cdot 1 = 2 \\X_2 = (2)^2\cdot X_1 = (2)^2 \cdot (2)= 8 \\X_3 = (2)^3\cdot X_2 = (8)(8)=64 \\ X_4 = (2)^4 \cdot X_3 = 16 \cdot 64 = 1024 } \]

Best ResponseYou've already chosen the best response.4@zzr0ck3r How about the nth term of the series?

Best ResponseYou've already chosen the best response.4for example 1 + 2 + 3 + 4 + ... 1 is the first term 2 is the second term 3 is the third term. etc It would just be easier to say the nth term of the sequence whose terms are come from a series.

Best ResponseYou've already chosen the best response.0yes for sure "term" makes sense, but as the question was phrased I was not sure if they were asking about the nth element in the sequence of partial sums of the series or just the nth element in the sequence.

Best ResponseYou've already chosen the best response.4I don't think she meant partial sum
