Question

$2y8912x \times 9( + 13 - 1)6x6 =$
​

Answer 1

Given terms are: 9, 13, 21, 37, 69, 132, 261

Here, the difference between the consecutive terns of the series is +4, +8, +16, +32, +64, +128.

Clearly, 69 + 64 = 133.

Therefore, the number 132 is to be replaced by 133.

Hence, option (D) is the correct answer.

Answer 2

Answer:

7n + 5 = 7 × (−2) + 5 = −14 + 5 = −9 ≠ 19 ... Therefore, p = 1 is not a solution of the given equation, 4p − 3 = 13.
