Final answer:
The series can be written using summation notation as ∑(3n + 4) for n = 1 to 12.
Step-by-step explanation:
The series can be written using summation notation as follows:
The general term of the series can be represented as an = 7 + (3(n-1)), where n represents the number of terms.
The summation notation of the series is: ∑(7 + (3(n-1))) for n = 1 to 12.
This can also be written as: ∑(7 + 3n - 3) for n = 1 to 12.
By simplifying, we get: ∑(3n + 4) for n = 1 to 12.
