Utilize our Harmonic sequence calculator tool for finding the sum of n terms of harmonic sequence when n=6, a=4, and d = 2 easily and quickly. So that you will get the result of 1/54.0.
Sum of first 6 terms of Harmonic Sequence of a = 4, n=6, and d=2 is 0.80472
Steps to find sum of n terms of harmonic sequence:
sum of n terms of harmonic sequence formula:-
Sn = `(1/d)*ln( (2*a+(2*n-1)*d)/(2*a-d) )`
where:
- sn is the sum of n terms
- a is first term
- n is total number of terms
- d is common difference
Input values are:-
a = 4
n = 6
d = 2
Put values into formula
S6 = `(1/d)*ln( (2*a+(2*n-1)*d)/(2*a-d) )`
S6 = `(1/2)*ln( (2*4+(2*6-1)*2)/(2*4-2) )`
S6 = 0.80472
Following are the step by step process to find the sum of N terms in a harmonic sequence easily by hand.
- Firstly, Write down the values that were given in the problem, such as a = 4, n=6, and d=2.
- As we know that arithmetic progression is the reciprocal of harmonic progression.
- Apply the formula of sum of n term of Arithmetic Progression, i.e., Sn = n/2[2a + (n − 1) × d]
- Substitute the values in the formula, i.e., Sn = 6/2[2*4 + (6 − 1) × 2].
- Simplify the equation, i.e., Sn = 6/2[2*4 + (6-1) × 2] = 54.0
- At last , the sum of n terms of Arithmetic progression is 54.0.
- Finally, the result of sum of n terms of Harmonic sequence is 1/54.0
