Given:

A sequence of numbers 12, 26, 312, 420, ____, 642, 756.

To Find:

The missing number __, which satisfies the series.

Solution:

The given sequence can be solved by developing a common logic between every term.

1. The second term of the sequence is obtained using the logic,

=> 26 = (tens digit of first number + 1)(units digit of first number +4).

2. The third term of the sequence is obtained using the logic,

=> 312 = (tens digit of second number + 1)(units digit of second number +6).

3. The fourth term of the sequence is obtained using the logic,

=> 420 = (tens digit of third number + 1)(units digit of third number +8).

4. The seventh term of the sequence is obtained using the logic,

=> 756 = (tens digit of sixth number + 1)(units digit of sixth number +14).

5. Using the above pattern, the unknown term can be calculated,

=> Unknown term = (tens digit of fourth number + 1)(units digit of sixth number + 10),

=> Unknown term = Hundreds place =(4+1),  remaining digits(20+10),

=> Unknown term = 530.

Therefore, the missing number in the series is 530. Option C is the correct answer.
