Multiple Choice

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

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