Questions & Step-by-Step Solutions
If the first term of a harmonic progression is 5 and the common difference of the corresponding arithmetic progression is 2, what is the second term of the harmonic progression?
Step 1: Identify the first term of the harmonic progression, which is given as 5.
Step 2: Understand that the harmonic progression is related to an arithmetic progression. The common difference of the corresponding arithmetic progression is given as 2.
Step 3: The first term of the arithmetic progression (AP) is the reciprocal of the first term of the harmonic progression (HP). So, the first term of the AP is 1/5.
Step 4: To find the second term of the AP, add the common difference (2) to the first term of the AP: 1/5 + 2.
Step 5: Convert 2 into a fraction with a denominator of 5: 2 = 10/5. Now, add 1/5 + 10/5 = 11/5.
Step 6: The second term of the harmonic progression is the reciprocal of the second term of the arithmetic progression. So, take the reciprocal of 11/5, which is 5/11.
Step 7: The second term of the harmonic progression is 5/11, which is approximately 0.45.
