No, two argon atoms cannot form a covalent bond to give Ar2. Argon is a noble gas with a full valence shell of electrons, making it very stable and unreactive. It does not readily form bonds with other atoms.

Ar2 (argon) is incorrect as noble gases do not form stable diatomic molecules. Cu2 (copper) is incorrect as copper typically forms ions with a +1 or +2 charge, not as a diatomic molecule. I2 (iodine) and O2 (oxygen) are correct formulas for elements iodine and oxygen respectively.
Argon represents an atom. It is a noble gas with the chemical symbol Ar and atomic number 18. Argon exists as single atoms and does not form molecules in its natural state.
Short answer: It doesn't have that many; it's a noble gas. Long answer: Argon fluorohydride, HArF, has tentative stability under -233 Celsius. A few Van der Waals molecules containing argon are known (Ar2, H2-Ar, C6H6-Ar), and the fullerene (Ar@C60) is known--but the last four are not true "compounds". Argon is a noble gas, having 8 electrons in its outer electron shell, so other atoms have to force that shell to expand for any compounds to form. So, only extreme conditions with the strongest electron-drawing element in existence can crack argon.
The sum of the series a + ar + ar2 + ... is a/(1 - r) for |r| < 1

A dongle is a device that is attached to a computer's I/O (input/output) port to release access or operation of software or hardware. Without a dongle, the software or hardware is rendered useless. The term "AR2" means "Action/Replay 2", a feature used in video games to store game play, codes, characters etc. Closest match is a memory card. So, putting the two together, an AR2 dongle is hardware that unlocks features or play of game software.
There is no conclusion to the Fibonacci sequence - it continues on infinitely. The conclusion is that successive terms tend to a constant ratio with one another. So if a is one term, the next is ar and the one after that is ar2. Then from the rule that any term is the sum of the previous two, ar2=ar +a, which means r2-r-1=0 so r =(1+sqrt5)/2 (the golden ratio). There is no end to this series.

The geometric distribution is: Pr(X=k) = (1-p)k-1p for k = 1, 2 , 3 ... A geometric series is a+ ar+ ar2, ... or ar+ ar2, ... Now the sum of all probability values of k = Pr(X=1) + Pr(X = 2) + Pr(X = 3) ... = p + p2+p3 ... is a geometric series with a = 1 and the value 1 subtracted from the series. See related links.
It is a number, r, which is greater than 1, such a given variable increases by a multiple r over each unit of time.So, over a set of times, the variable A would beA, Ar, Ar2, Ar3, ... , Arn-1, ...
Not sure about this question. But, a geometric sequence is a sequence of numbers such that the ratio of any two consecutive numbers is a constant, known as the "common ratio". A geometric sequence consists of a set of numbers of the form a, ar, ar2, ar3, ... arn, ... where r is the common ratio.
The formula to find the sum of a geometric sequence is adding a + ar + ar2 + ar3 + ar4. The sum, to n terms, is given byS(n) = a*(1 - r^n)/(1 - r) or, equivalently, a*(r^n - 1)/(r - 1)

The use of the expression 'common ratio' means that the sequence is a Geometric series where the terms are of the form a, ar ar2, ar3, ...arn-1 where a is the first term and r is the common ratio. The third term, a3 = 3 x 32 = 3 x 9 = 27
