7. Arithmetic series. An arithmetic series allows to model different problems that can model physical phenomena and is defined by: + (+ ) + (+ 2) + (+ 3) + + [(+ (1)] where a is the first term, d is the "common difference" and n is the number of terms that go to add Using this information, design and implement a C++ function that uses a loop to display each term and to determine the sum of the arithmetic series, if a = 1, d = 3 and n = 25. For the display of the terms, use a format similar to: Term i: 999 where i is the number of the term that must start with 1 and 999 is the calculated value of the i-th finished. At the end of the loop, the function should display the total sum of the series: Total value of the series: 999 No data is requested from the user.
