Final answer:
The correct summation expression for the series 4/3 + 2/4 + ... + (5 - 1/n) is ∑ (1 - 1/n), which represents the series' terms correctly.
Step-by-step explanation:
The student is asking to identify the correct summation expression for a given series. To find the sum, we should closely observe the pattern of the series and match it to the correct expression.
The provided series is 4/3 + 2/4 + ... + (5 - 1/n). When simplified, this is equivalent to 1 + 1/3 + 1/2 + 1/4 + ... + 4 - 1/n. Examining the possible options:
- a) ∑ (1 - 1/n)
- b) ∑ (1 + 1/n)
- c) ∑ (2 - 1/n)
- d) ∑ (2 + 1/n)
It is clear that the correct expression for this series is option a) ∑ (1 - 1/n), as this expression represents the series' terms correctly.
