**Creating a Sum of Sequence Using Method4** The task is to write a method named `method4` that accepts an integer parameter `n` and returns the sum of the first `n` terms of a specific sequence. The sequence for the sum is as follows: \[ 1 + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \ldots + \frac{1}{n} \] ### Example Calculations 1. **For `method4(2)`**: - The calculation is: \[ 1 + \frac{1}{2} = 1.5 \] - Therefore, `method4(2)` will return **1.5**. 2. **For `method4(15)`**: - The calculation expands to: \[ 1 + \frac{1}{2} + \frac{1}{3} + \ldots + \frac{1}{14} + \frac{1}{15} \] - The final result will be **3.3182289932289937**. ### Note - It is assumed that the parameter `n` is nonnegative. In this method, you input the desired number of terms in the sequence, and it computes the sum of these terms following the harmonic progression described above.
