The coefficient of in the infinite series expansion of , for is
Explanation for the correct option:
Finding coefficient of :
Using infinite expansion series where
Given, , for
Using series which is One of the most fundamental subjects in Arithmetic is sequence and series.
A sequence is an itemized collection of elements that allows for any type of repetition, whereas a series is the total of all elements.
One of the most common instances of sequence and series is an arithmetic progression.
Rearranging the series gives
The standard expansion of is given by
Coefficient of in expression will be
Hence, option (B) is the correct answer.
