The sets

{S_1},{S_2},{S_3} \ldots

are given by

{S_1} = \left\{ {\frac{2}{1}} \right\},{S_2} = \left\{ {\frac{3}{2},\frac{5}{2}} \right\},{S_3} = \left\{ {\frac{4}{3},\frac{7}{3},\frac{{10}}{3}} \right\},{S_4} = \left\{ {\frac{5}{4},\frac{9}{4},\frac{{13}}{4},\frac{{17}}{4}} \right\}, \ldots

Then, the sum of the numbers in the set

{S_{25}}

View answer and explanation

Correct option: D

326

Option D (326) is correct because the sum of the arithmetic series in set S_{25} is calculated correctly using the AP sum formula.
