Explanation:

Let's look for a pattern in the series:

25, 34, 52, ?, 160, 304

- Let's find the differences between the numbers:

- 34 - 25 = 9

- 52 - 34 = 18

- ? - 52 = ?

- 160 - ? = ?

- 304 - 160 = 144

- The differences so far: 9, 18, ?, ?, 144

- Let's check the progression: 9, 18, ?, ?, 144.

- Notice: 9 x 2 = 18, 18 x 2 = 36, 36 x 2 = 72, 72 x 2 = 144

So the pattern in differences seems to double each time.

- So after 18 comes 36:

- 52 + 36 = 88

- Then after 36, the next difference should be 72:

- 88 + 72 = 160

Let's check option 1:

- Option 1: 88

Other options:

- Option 2: 80 (does not fit the doubling pattern)

- Option 3: 99 (does not fit the doubling pattern)

- Option 4: 95 (does not fit the doubling pattern)

Correct answer is Option 1: 88
