Best ResponseYou've already chosen the best response.3Tn = 7n^2  n^3 T1 = 7(1)^2  (1)^3 = 6 T2 = 7(2)^2  (2)^3 = 20 .... ... T6 = 7(6)^2  (6)^3 = 78 T7 = 7(7)^2  (7)^3 = 0 so, it is T6 = 78

Best ResponseYou've already chosen the best response.0@RadEn's reasoning checks out, his answer should be 36 though. \(7(6^2)6^3=252216=36\)

Best ResponseYou've already chosen the best response.0because if we put n=6,the answer comes to be is 36 but in actual(followed by series)the answer would be 50

Best ResponseYou've already chosen the best response.0iska matla agar hum uske tarike se follow karien to iska answer 50 aana chaihye series ke hisaab se lekin actual main 36 aa raha h..... iska method thode se hi digits ke liye apply hota h
