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.
Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r. Example. Write the first five terms of a geometric sequence in which a 1 =2 and r=3. We use the first given formula: Just as with arithmetic series it is possible to find the sum of a geometric series. It is found by using one of the following formulas: Videolesson: use the formula for the sum of a geometric series to determine the sum when a 1 =4 and r=2 and we have 12 terms. 1  Pre-Algebra. 2  Algebra 1. 3  Algebra 2. 4  Geometry.
