Let’s look at the given series:

28, 40, 25, ?, 22, 46

- Let's examine the pattern by comparing alternate numbers:

- 28 (1st), 25 (3rd), 22 (5th): Each time, we subtract 3. (28-3=25, 25-3=22)

- For the 2nd group: 40 (2nd), ?, 46 (6th)

- Here, let's see the step from 40 to 46: We add 6.

- So to keep the pattern, we should subtract 3 from 40 to get ? (since other group was “-3”),

- However, checking the direct arithmetic progression:

- 2nd term ? 4th term ? 6th term: Let's check for another arithmetic progression.

- 40 to 46: +6

- Guess in between: 40, ?, 46. So, if evenly spaced: difference of 3 each time: 40+3=43, 43+3=46.

- So, 43 fits there.

Let's review the options:

- Option:1, 41 — doesn't match the pattern.

- Option:2, 43 — fits the sequence perfectly.

- Option:3, 44 — difference doesn't match with others.

- Option:4, 42 — difference doesn't match.

Correct answer is: Option 2, 43
