664/2 = 332,
340/2 = 170,
Now ?/2 = 89,
That is 178/2 = 89.
So, the ans is : 178
340/2 = 170,
Now ?/2 = 89,
That is 178/2 = 89.
So, the ans is : 178

664, 332, 340, 170, ___, 89.
89 * 2 = 178,
170 * 2 = 340,
332 * 2 = 664.
89 * 2 = 178,
170 * 2 = 340,
332 * 2 = 664.

I think the correct answer is 85 because the second number on the series from left to right 332 is less than the third number which is 340. If the same rule is applied from right to left, then 85 is the best answer.

I Agree that answer:
664, 332, 340, 170, ____, 89
After 2 number multiply by 2,
Like 332*2 = 664.
170 *2 = 340.
89*2 = 178 So the answer is 178.
664, 332, 340, 170, ____, 89
After 2 number multiply by 2,
Like 332*2 = 664.
170 *2 = 340.
89*2 = 178 So the answer is 178.
