6, 14, 36, 98, 276, ?  Choose one:
A) 657 B) 794 C) 453 D) 564 E) 123
B   794   The nth term in the series is given by the sum of x^n for x in the range 1 to 3, i.e. 1^n + 2^n + 3^n.   Thus the first term is 1^1 + 2^1 + 3^1 = 1 + 2 + 3=

<output>6</output>
6,   the second term is 1^2 + 2^2 + 3^2= 1 + 4 + 9= 
<gadget id="calculator">1 + 4 + 9</gadget>
<output>14</output>
14,   and so on.   The sixth term is then 1^6 + 2^6 + 3^6= 1 + 64 + 729=

<output>794</output>
794.
