Linux isnt even suppose to be even close to Unix. Linux is based off of Minix, a micro-kernel architectureâ¦ Minix and Unix are 2 completely different cores, as different as Windows and Mac OS X, Windows and Linux, and Mac and Linux. BSD is a different beast, based on Unix, Linux is based on Minix, OS X is based on BSD.
1 A geometric sequence is one in which the same number is multiplied or divided by each element to get the next element in the sequence. 2  2, 4, 8, 16, ... is a geometric sequence.
For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2. Examples of a geometric sequence are powers r of a fixed number r, such as 2 and 3. The general form of a geometric sequence is. where r â  0 is the common ratio and a is a scale factor, equal to the sequence's start value.
