Which expression defines the arithmetic series 2.3 + 2.6 + 2.9 + for five terms

Option C is the answer.

Step-by-step explanation:

Given arithmetic series is 2.3 + 2.6 +2.9 + ......... 5 terms

Since this series is an arithmetic series so explicit formula of series will be where a is the first term, d is the common difference and n is the number of term.

Therefore, we replace the values a = 2.3, and d = (2.6 - 2.3) = (0.3)

expression will be

Option C is the answer.
