Find the correct password.

• A. 53654
• B. 54536
• C. 36554
• D. 54365

Answer 1

The correct option is D 54365

The first two-digits:
For this, we have to find the next number of the series: 40, 42, 46, 48, 52

We can see that it is an alternating number addition series, i.e., first 2 is added then 4 is added.

40 + 2 = 42
42 + 4 = 46
46 + 2 = 48
48 + 4 = 52

So, the next number is:
52 + 2 = 54

Thus, the first two digits are 54.

The next two digits:
Value of 3 + 3 = 6
The product of 6 with itself is:
$6\times 6=36$

The last digit:
The quotient of 45 ÷ 9 is 5.

So, the password is 54365.
