Select the option that will fill in the blank and complete the series.

​$$\frac{1}{16}$$, $$\frac{1}{4}$$, 1, ___, 16

Given: $$\frac{1}{16}$$, $$\frac{1}{4}$$, 1, __, 16

Logic: Multiply the given term in the series by 4 to get the next term in the series.

​$$\frac{1}{16}$$ $$\times$$ 4 = $$\frac{1}{4}$$

$$\frac{1}{4} \ \times$$ 4 = 1

4 $$\times$$ 4 = 16

So, 4 is the missing number in the series.

Thus, the correct answer is (b).
