1+1/2+1/3+...+1/n sum formula
1+1/2+1/3+...+1/n sum formula-Then Prove, Using Induction, That Your Formula Is Correct 1/1 2 = 1/2, 1/1 2 1/2 3 = 1/2 1/6 = 2/3, 1/1 2 1/2 3 1/3 4 = 2/3 1/12 = 8/12 1/12 = 3/4, And 1/1 2 1/2 3 1/3 4 1/4 5 = 3/4 1/ = 15/ 1/ = 4/5 This Leads Us To Suspect ThatThe series converges with sum cos1 1 (b

Therefore we subtract off the first two terms, giving ∞ ∑ n = 2(3 4)n = 4 − 1 − 3 4 = 9 4 This is illustrated in Figure Since r = 1 / 2 < 1, this series converges, and by Theorem 60, ∞ ∑ n = 0(− 1 2)n = 1 1 − ( − 1 / 2) = 2 3 The partial sums of this series are plotted in Figure (a){n(n1)/2}² Summation of n Numbers Formula The sum of "n" numbers formulas for the natural numbers is given as n(n 1)/2 Sum of Even Numbers Formula Sum of even numbers formulas for first n natural number is given S = n(n 1) Sum of even numbers formula for first n consecutive natural numbers is given as S e = n (n 1) Sum of OddNot a problem Unlock StepbyStep
S n – S n4 = n (n – 1) (n – 2) (n – 3) = 4n – (1 2 3) Proceeding in the same manner, the general term can be expressed as According to the above equation the n th term is clearly kn and the remaining terms are sum of natural numbers preceding itThe partial sums form a convergent sequence 1, 2/3, 1, 4/5, 1, 6/7, The sequence converges to 1 Grouping pairs of successive terms leads to every other sum being omitted but does not change the fact of convergence, nor affects the limit itself The second series to consider is 1/1 2/3 2/3 3/5 3/5 4/7 I won't go into a full explanation as it too complex But essentially Sum of the reciprocals sum_(r=1)^n \ 1/r = H_n Where H_n is the nth harmonic number Sum of the reciprocals of the squares sum_(r=1)^n \ 1/r^2 = pi^2/6 sum_(r=1)^n \ (beta(k,n1
The summation math\displaystyle H_{n}=\frac{1}{1}\frac{1}{2}\frac{1}{3}\ldots\frac{1}{n} \tag*{}/math is the finite harmonic series, where mathH_{n}/mathWrite The First Four Terms Write the first four terms of the sequence defined by the recursion formula Since we already know the first term is 3, we begin by plugging in n=2, then n=3 and finally n=4 So our first 4 terms are 3, 8, 13, and 18 8 5 3 5 5 2 2 1 2 1 2 2 a a a a a a 13 5 8 5 5 3 3 2 3 1 3 3 a a a a a a 18 5 13 5 5 3 4 3 4 1 4 4 a aSo we can construct f(n) = f(n1) 1/(n(n1)) Now look at the small values of n f(1) = 1/2, f(2) = 1/2 1/6 = 2/3, f(3) = 2/3 1/12 = 3/4, f(4) = 3/4 1/ = 4/5, etc So for the first few small values of n, we have proven by demonstration that f(n) = n / (n1)

n * (1 1/2 1/3 1/4 1/n) Unlike the geometric series the harmonic series does not converge, but it diverges as we add more terms The partial sums of first n terms can be bounded above and below by ln n C , hence the time complexity of the entire algorithm is 4 Work any of your defined formulas to find the sum Once you've plugged in the integer, multiply the integer by itself plus 1, 2 , or 4 depending on your formula Then divide your result by 2 or 4 to get the answer For the example of consecutive formula 100∗101/2, multiply 100 by 101 to get sum_(i=1)^n (1i/n)(2/n) = (3n1)/n lim_(n rarr oo)sum_(i=1)^n (1i/n)(2/n) = 3 > Let S_n = sum_(i=1)^n (1i/n)(2/n) S_n = sum_(i=1)^n (2/n(2i)/n^2) S_n = 2/n
