Find out the missing term of the number series given below.

54, 67, 50, 63, 46, ?

The correct option/answer is 59.

To find the missing term of the number series, let us analyze the pattern of the given numbers:
54, 67, 50, 63, 46, ?

Let us look at the differences between consecutive terms in the series:

$54+13=67$

$67-17=50$

$50+13=63$

$63-17=46$

We can observe that the pattern alternates between adding 13 and subtracting 17:
1st term to 2nd term: +13
2nd term to 3rd term: -17
3rd term to 4th term: +13
4th term to 5th term: -17

Following this alternating pattern, the next operation to get the 6th term from the 5th term must be to add 13:

$46+13=59$

Alternatively, we can view this as two interleaved series:
First series (at odd positions): 54, 50, 46 (where each term decreases by 4)
Second series (at even positions): 67, 63, ? (where each term decreases by 4)

Following the second series, the next term is:

$63-4=59$

Thus, the missing term is 59.
