Study the sequence/pattern of letters or numbers carefully to work out the pattern on which it is based, and answer what the next item in the sequence must be.

For example, the sequence ‘A,C,E,G,?’ has odd numbered letters of alphabet, therefore, the next item must be ‘I’.

8, 16, 28, 44 ?

The correct option is 64.

Let's analyze the given numerical sequence step-by-step to find the underlying pattern:

The sequence is: 8, 16, 28, 44, ?

First, let's calculate the difference between consecutive terms in the sequence:

First difference (between 16 and 8):

$16-8=8$

Second difference (between 28 and 16):

$28-16=12$

Third difference (between 44 and 28):

$44-28=16$

Now, look at the pattern in the differences:

8, 12, 16

We can see that each difference increases by 4:

$12-8=4$

$16-12=4$

Following this pattern, the next difference to add to 44 should be:

$16+4=20$

Therefore, the next number in the sequence is:

$44+20=64$
