Statement 1:Three consecutive binomial coefficients are always in A.P. Statement 2: Three consecutive binomial coefficients are not in H.P. or G.P.

If the binomial coefficients of three consecutive terms in the expansion of (a+x)^n are in the ratio 1:7 :42 , then find n .

In the expansion of (3^(-x//4)+3^(5x//4))^(n) the sum of binomial coefficient is 64 and term with the greatest binomial coefficient exceeds the third by (n-1) , the value of x must be

If the three consecutive coefficients in the expansion of (1+x)^n are 28, 56, and 70, then the value of n is.

In the binomial coefficients of (1 + x)^(n) , the coefficients of the 5th, 6th and 7th terms are in AP Find all values of n.

Statement 1: Out of 5 tickets consecutively numbered, three are drawn at random. The chance that the numbers on them are in A.P. is 2/15. Statement 2: Out of 2n+1 tickets consecutively numbed, three are drawn at random, the chance that the numbers on them are in A.P. is 3n//(4n^2-1)dot

The coefficients of three consecutive terms in the expansion of (1 + a)^n are are in the ratio 1: 7: 42 Find n.
