If a, b and c are three consecutive coefficients terms in the expansion of `(1+x)^n` , then find n.

If a,b and c are three consecutive terms in the expansion of (1+x)^(n), then find n.

If a,b,c,d be four consecutive coefficients in the binomial expansion of (1+x)^(n) , then value of the expression (((b)/(b+c))^(2)-(ac)/((a+b)(c+d))) (where x gt 0 and n in N ) is

If a,b,c,d be four consecutive coefficients in the binomial expansion of (1+x)^(n) , then value of the expression (((b)/(b+c))^(2)-(ac)/((a+b)(c+d))) (where x gt 0 and n in N ) is

If a,b,c,d be four consecutive coefficients in the binomial expansion of (1+x)^(n) , then value of the expression (((b)/(b+c))^(2)-(ac)/((a+b)(c+d))) (where x gt 0 and n in N ) is

If a,b,c,d be four consecutive coefficients in the binomial expansion of (1+x)^(n) , then value of the expression (((b)/(b+c))^(2)-(ac)/((a+b)(c+d))) (where x gt 0 and n in N ) is

If the three consecutive coefficients in the expansion of (1 + x)^n are in the ratio 1: 3 : 5, then the value of n is:

if a,b,c and d are the coefficient of four consecutive terms in the expansion of (1+x)^(n) then (a)/(a+b)+(C) /(c+d)=?
