Final answer:
The given expression 3.5 + 4 + 4.5 + 5 + 5.5 can be represented in sigma notation as: Σ(n=1 to 5) (n+2.5). The sum of the expression is 17.5.
Step-by-step explanation:
The given expression 3.5 + 4 + 4.5 + 5 + 5.5 can be represented in sigma notation as:
Σ(n=1 to 5) (n+2.5)
Here's the step-by-step explanation:
- Start with the lower limit of the sigma, which is 1 in this case.
- Plug in the value of n for each term and sum them up.
- For the given expression, the sum would be:
(1+2.5) + (2+2.5) + (3+2.5) + (4+2.5) + (5+2.5) = 17.5
