Identifying the pattern, it is found that the correct option is:
A. As the number of circles increases, the number of regions increases by successive multiples of 2 each time.
- With 6 circles, there are going to be 31 regions.
------------------------
- With 1 circle, there is 1 region.
- With 2 circles, there are 3 regions. Thus, it increased by 2.
- With 3 circles, there are 7 regions. The increase was of 7 - 3 = 4.
- With 4 circles, there are 13 regions. The increase was of 13 - 7 = 6.
- With 5 circles, there are 21 regions. The increase was of 21 - 13 = 8.
(2,4,6,8) are consecutive multiples of 2, thus, the correct option is:
A. As the number of circles increases, the number of regions increases by successive multiples of 2 each time.
------------------------
- The next multiple of 2 is 10.
- Thus, with 6 circles, there will be 21 + 10 = 31 regions.
