If for some positive integer n, the coefficients of three consecutive terms in the binomial expansion of (1 + x) n + 5 are in the ratio 5 : 10 : 14, then the largest coefficient in this expansion is :

If for some positive integer $n$, the coefficients of three consecutive terms in the binomial expansion of $(1+x)^{n+5}$ are in the ratio $5: 10: 14$, then the largest coefficient in this expansion is :
