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.
The sum of the terms of the geometric sequence is known as a geometric series; Sn = ar+ ar2 + ar3 + â¯ + arn = âi=1ân ari. The sum of the geometric series can be calculated using the following formula. Sn = a(1-rn)/(1-r); where a is the initial term and r is the ratio. If the ratio, r â¤ 1, the series converges.
