MathematicsBinomial TheoremJEE Main 2025

Let the coefficients of three consecutive terms , and in the binomial expansion of be in a G.P. and let p be the number of all possible values of r. Let q be the sum of all rational terms in the binomial expansion of . Then p + q is equal to :

Answer: (1)

Solution

No value of r satisfies GP condition, so p=0. Rational terms give q=27+256=283. p+q=283
