Step 1 :\(\text{integer_sum} = 4 - 2 + 1 = 3\)
Step 2 :\(\text{fraction_sum} = -\frac{1}{2} + \frac{1}{4} - \frac{1}{8} = -0.375\)
Step 3 :\(\text{total_sum} = \text{integer_sum} + \text{fraction_sum} = 3 + (-0.375) = 2.625\)
Step 4 :\(\boxed{\text{Final Answer: The sum of the given series is 2.625}}\)
