Q13/070) Find the largest coefficient in the expansion of (1+x)^n given that the sum of the coefficients of the terms in the expansion is 4096



We get sum of the coefficient by putting x = 1

So (1+1)^n = 4096 or 2^n = 4096 = 2 ^12 => n = 12

The coefficients are 12Cn and as 12 is even largest coefficient is 12C6
