A geometric series begins with 4, ends with 1/64, and has a common ratio of one half. Which geometric series is correct?

• 4+2+1+1/2+1/4+1/8+1/16+1/32+1/64

• 4-2+1-1/2+1/4-1/8+1/16-1/32+1/64

• 4+2+1/2+1/4+1/8+1/16+1/32+1/64

• 4+2+1+1/2+1/4+1/16+1/64

Build the series knowing that it has 5 terms, starts with -2 and has a common ratio of -4.

• -2 - 8 - 32 - 128 - 512

• -2 + 8 - 32 + 128 - 512

• 2 + 8 + 32 + 128 + 512

• -2 + 8 + 32 - 128 + 512
