The number of terms in the expansion of `(x+a)^100+(x-a)^100` after si

1.	The number of terms in the expansion of `(x+a)^100+(x-a)^100` after simplificationA. 202B. 101C. 51D. 50
Answer» Correct Answer - C `(x+a)^(100)+(x-a)^(100)` Simple logic is we get `.^(n)c_(0),.^(n)c_(2),.^(n)c_(4).....^(n)C_(100)` in this expansion. The number of terms from `.^(n)c_(0) "to" .^(n)c_(100) "are 51"`
