AP EAMCET2004MathematicsBinomial Theorem
The binomial coefficients which are in decreasing order are
Options
- A¹⁵ C₅, ¹⁵ C₆, ¹⁵ C₇
- B15 10 , ¹⁵ C₉, ¹⁵ C₈
- C¹⁵ C₆, ¹⁵ C₇, ¹⁵ C₈
- D¹⁵ C₇, ¹⁵ C₆, ¹⁵ C₅
Correct answer
D. ¹⁵ C₇, ¹⁵ C₆, ¹⁵ C₅
Step-by-step solution
The series of binomial coefficient is ¹⁵ C₀, ¹⁵ C₁, ¹⁵ C₂ ¹⁵ C₇, ¹⁵ C₈, ¹⁵ C₉ . . 15 14 , 15 15 Form the above discussion, we can say that decreasing series is ¹⁵ C₇, ¹⁵ C₆, ¹⁵ C₅ therefore option (4) is correct.
