Final Answer:

The 12th partial sum of the series
\( (3)/(2) + (7)/(3) + (19)/(6) + \ldots \) can be expressed as
\( \sum_(n=1)^(12) (2n-1)/(2(n-1)) \).

Step-by-step explanation:

The 12th partial sum of the series
\( (3)/(2) + (7)/(3) + (19)/(6) + \ldots \) can be expressed using summation notation as:


\[ S_(12) = \sum_(n=1)^(12) (2n-1)/(2(n-1)) \]

Step-by-step explanation:

  1. The series starts from n = 1 and goes up to n = 12, as indicated by the subscript 12 in
    \( S_(12) \).

  2. \( (2n-1)/(2(n-1)) \) represents the general term of the series. For each term with index n, the numerator is
    \( 2n-1 \) and the denominator is
    \( 2(n-1) \).
  3. The sigma notation
    \( \sum \) is used to denote the summation. In this case, it adds up the terms for each n from 1 to 12.

In conclusion,
\( S_(12) \) represents the sum of the first 12 terms of the given series using the specified formula.
