Question 16

Multiple Choice

Write the sum using sigma notation. Begin with k=0k = 0 . 190191+192193+1911\frac { 1 } { 9 ^ { 0 } } - \frac { 1 } { 9 ^ { 1 } } + \frac { 1 } { 9 ^ { 2 } } - \frac { 1 } { 9 ^ { 3 } } + \ldots - \frac { 1 } { 9 ^ { 11 } }


A) k=01019k\sum _ { k = 0 } ^ { 10 } - \frac { 1 } { 9 ^ { k } }
B) k=011(19) k+1\sum _ { k = 0 } ^ { 11 } \left( - \frac { 1 } { 9 } \right) ^ { k + 1 }
C) k=010(19) k+1\sum _ { k = 0 } ^ { 10 } \left( - \frac { 1 } { 9 } \right) ^ { k + 1 }
D) k=01119k\sum _ { k = 0 } ^ { 11 } - \frac { 1 } { 9 ^ { k } }
E) k=011(19) k\sum _ { k = 0 } ^ { 11 } \left( - \frac { 1 } { 9 } \right) ^ { k }
