Sum of Finite Series

Is this sum finite or infinite?

• Finite, because there are only 11 terms to add up.

• Infinite, because there are an infinite number of terms to add up.

This summation is the same as which series?

• 1 + 2 + 3 + 4 + 5 + 6

• (1 - 2) + (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) + (6 - 2)

• (1 - 2) + (6 - 2)

• (1 - 2) + (2 - 2) + (3 - 2) + (4 - 2)
