1.0 Geometric

A geometric sequence is similar to an arithmetic sequence. Instead of having the same difference between the terms, we have the same ratio. for example: 2, 4, 8, 16, 32, 64 ... is a geometric sequence and the ratio is 2.
Here is a geometric sequence with a ratio of 6:
2, 12, 72, 432, 2592, 15552...
when we add up all the terms of a geometric sequence we get a series.
This is a series: 1+2+4+8+16+32+64+128...
