(B) The given series is $2, 5, 17.5, 43.75, ?$.Let us analyze the pattern between consecutive terms:$2 	imes 2.5 = 5$$5 	imes 3.5 = 17.5$$17.5 	imes 2.5 = 43.75$Following the pattern of multiplying by $2.5$ and $3.5$ alternately, the next step is to multiply by $3.5$:$43.75 	imes 3.5 = 153.125$Therefore, the missing number is $153.125$.

$2, 5, 17.5, 43.75, ? (\text{in } 153.125)?$
