What will come in place of the question mark (?) in the following number series ?
11 27 ? 107 171 251
The pattern followed is:
$$11+1\times16 = 11+16 = 27$$.
$$27+2\times16 = 27+32 = 59$$.
$$59+3\times16 = 59+48 = 107$$.
$$107+4\times16 = 107+64 = 171$$.
$$171+5\times16 = 171+80 = 251$$.
Hence, Option D is correct.
