Order the set from least to greatest. The number in the middle, or the mean of the two numbers in the middle, is the median. That is, if S is the set, then for #S = 2n - 1, Sn is the median, while for #S = 2n, (Sn-1 + Sn)/2 is the median.
A series is a special case of a sequence where the n'th term is the sum of n numbers a1, a2, ..., an. In other words, it is a sequence in the form S1 = a1 S2 = a1 + a2 S3 = a1 + a2 + a3 ... Sn = a1 + a2 + ... + an
the formula is: Sn= n [2(A1)+(n - 1)d] 2 for example the given sequence is when A1 = 4 and n = 10 when d = 2 here is the solution: Sn = 4 [2(4)+(10 - 1)2] 2 Sn= 2 [6+(9)(2) Sn = 2 [6+18] Sn = 2 (24) Sn = 48 see?
200, 20, 2, 0.2 Here you have 4 terms. Add them together, and you find the sum of these four terms. If you need to find the sum of some other terms, i.e 8 terms, then you can use the formula Sn = [a1(r^n - 1/(r - 1) where n = 8, a1 = 200, and r = 1/10.
Zero. This is true for all elements inn their elemental form.
Yes: Stannous: Sn2+ or Sn(II)-cation and Stannic Sn4+ or Sn(IV)-cation, like lead (Pb) does.
0 in the elemental form. +2 and +4 in its compounds
0 in elemental form, +2 and +4 in its compounds.
Not likely. No sn data in published form.
Tin atoms form two types of stable ions, Sn+2 stannous and Sn+4stannic.
If you have a look along the periodic table the whole left side (Groups 3-7) are non-metals (apart from Al, Ga, In, Sn, Tl, Pb, Bi) covalent bonds only form with non metals so this is where you'll find them all.
Ag
You will have to call Colt with the sn to find out.
