The first three terms in the expansion of a binomial are `1, 10 and 40`. Find the expansion.

If the first three terms in the expansion of (a + b)^(n) are 27, 54 and 36 respectively, then find a, b and n.

If the first three terms in the expansion of (1+ax)^n are 1,12 x , 64x^2 , find 'n' and 'a'

The first three terms in the expansion of (1+ax)^(n)(n!=0) are 1,6x and 16x^(2). Then find the value of a and n.

Consider the binomial expansion of (sqrt(x)+(1/(2x^(1/4))))^n n in NN, where the terms of the expansion are written in decreasing powers of x. If the coefficients of the first three terms form an arithmetic progression then the statement(s) which hold good is(are) (A) total number of terms in the expansion of the binomial is 8 (B) number of terms in the expansion with integral power of x is 3 (C) there is no term in the expansion which is independent of x (D) fourth and fifth are the middle terms of the expansion
