RadEnBest ResponseYou've already chosen the best response.3
Tn = 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

@RadEn's reasoning checks out, his answer should be 36 though. \(7(6^2)6^3=252216=36\)

because if we put n=6,the answer comes to be is 36 but in actual(followed by series)the answer would be 50

iska 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

yeah...this logic doesn't apply in NTSE STAGE 1

mayankdevnaniBest ResponseYou've already chosen the best response.0
i think there is another logic simpler logic for this
