Question

0.04, 0.09, 0.25, 0.49,____.
(1) 0.081
(2) 0.121
(3) 0.0121
(4) 0.81
​

Answer 1

we have to find the next term of 0.04, 0.09, 0.25, 0.49, ----

solution : this question is an example of logical reasoning, missing number series.

it can be solved just by getting appropriate relation between given terms.

so, let's find the relation between them.

0.04 = (0.2)² = (2/10)² = 2²/10²

0.09 = (0.3)² =(3/10)² = 3²/10²

0.25 = (0.5)² = (5/10)² = 5²/10²

0.49 = (0.7)² = (7/10)² = 7²/10²

here we see, numerators of all terms contain square of prime number so the next term also contains square of a prime number.

after 7, 11 is next prime number

so, next term = 11²/10² = 121/100 = 1.21

Therefore the next term must be 1.21
