Solution
In the given series,
$$\frac{664}{2}=332$$
$$332+8=340$$
$$\frac{340}{2}=170$$
$$170+8=178$$
$$\frac{178}{2}=89$$
The numbers in the series are divided by 2 and added with 8 alternately as shown above.
$$\therefore\ $$The required number in the series = 178
Hence, the correct answer is Option D
