HI Student,

The cofficient of middle term is greatest for an expansion in the form of (1+x)n . If n is odd there are even terms there will be 2 middle terms and if n is even there will be odd terms and there will be 1 middle term. Hence in the the above expression power is even middle term will be 2n+2Cn+1. This is the greatest coefficient,
