Find the Sum of n terms of Harmonic Sequence a = 4, n=10, and d=5

Sum of first 10 terms of Harmonic Sequence of a = 4, n=10, and d=5 is 0.70722

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 = 10

d = 5

Put values into formula

S10 = `(1/d)*ln( (2*a+(2*n-1)*d)/(2*a-d) )`

S10 = `(1/5)*ln( (2*4+(2*10-1)*5)/(2*4-5) )`

S10 = 0.70722

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=10, 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 = 10/2[2*4 + (10 − 1) × 5].
  • Simplify the equation, i.e., Sn = 10/2[2*4 + (10-1) × 5] = 265.0
  • At last , the sum of n terms of Arithmetic progression is 265.0.
  • Finally, the result of sum of n terms of Harmonic sequence is 1/265.0
