Question 9

# A series is given, with one number missing. Choose the correct alternative from the given ones that will complete the series.1, 0.25, 1/9, ? , 0.04, 1/36

Solution

Numbers of the form $$'\frac{1}{n^2}'$$ are written.

$$\frac{1}{1^2}$$ = 1

$$\frac{1}{2^2}$$ = $$\frac{1}{4}$$ = 0.25

$$\frac{1}{3^2}$$ = $$\frac{1}{9}$$

$$\frac{1}{4^2}$$ = $$\frac{1}{16}$$ = 0.0625

$$\frac{1}{5^2}$$ = $$\frac{1}{25}$$ = 0.04

$$\frac{1}{6^2}$$ = $$\frac{1}{36}$$

=> Ans - (A)
