First term [a]:
common difference[d]:
Total terms[n]:

### Steps to find sum of n terms of harmonic sequence:

sum of n terms of harmonic sequence formula:-

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 = 7

d = 5

Put values into formula

S7 = (1/d)*ln( (2*a+(2*n-1)*d)/(2*a-d) )

S7 = (1/5)*ln( (2*4+(2*7-1)*5)/(2*4-5) )

S7 = 0.63837

## How to Find the Sum of N terms of Harmonic Sequence of a = 4, n=7, and d=5?

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=7, and d=5.
• 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 = 7/2[2*4 + (7 − 1) × 5].
• Simplify the equation, i.e., Sn = 7/2[2*4 + (7-1) × 5] = 133.0
• At last , the sum of n terms of Arithmetic progression is 133.0.
• Finally, the result of sum of n terms of Harmonic sequence is 1/133.0
