Consider the expansion of `(2x-1)^(15)`A. Algebraically least coefficient is `T_(5)`B. Algebraically greatest coefficient is `T_(5)`C. Numerically greatest coefficient is `T_(6)`D. Numerically least coefficient is `T_(16)`

Answer» Correct Answer - B::C::D
`rle(n+1)/(1+|(x)/(y)|)`
`rle(16)/(1+|(2x)/(-1)|)`
`rle(16)/(3)=5`
`impliesT_(6)` gives numerically greatest coefficient
`T_(6)= .^(15)C_(5)(-1)^(5)(2)^(10)(x)^(10)`
`N.G.C= .^(15)C_(5)(2)^(10)`
`N.I.C=1`
`A.L.C= .^(15)C_(4)(2)^(10)`
`A.G.C= .^(15)C_(4)(2)^(11)`
