Which of the following is the correct expanded form for the series below?

–1 – 2 – 4 – 8 – 16
1 – 2 + 4 – 8 + 16
–2 – 4 – 8 – 16
–2 + 4 – 8 + 16

answer: first option i.e. 'a' is correct.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
