Explanation:

Let’s break this down:

- Here's the series: 10, 22, 35, 40, 72, 40, ?

- First, look for a pattern. Notice the “40” repeats, so there might be a cycle.

- Now, check the differences:

22 - 10 = 12

35 - 22 = 13

40 - 35 = 5

72 - 40 = 32

40 - 72 = -32

- See those “32” and “-32”? That looks like it repeats.

- If we keep the pattern, next should be "+" value for the repeated 40. Add 93 (since previous increase was 32, the other increases before were 12, 13, 5--they seem unrelated).

- Or maybe, more likely: alternate between adding a number and then repeating 40?

- Honestly, the pattern is tricky, and it seems every other number is 40 starting from the fourth term.

- From 40 to 72, we add 32, then 40, then probably add 93? But even then, only option 1 (143) fits: 40 + 103 = 143.

So checking options:

- Option 1: 143

- Option 2: 131

- Option 3: 134

- Option 4: 133

Re-checking math: nothing matches except 143 if you keep the 40 and up big—so the best fit is 143.

Correct answer: Option 1—143.

That’s your missing piece in the pattern.
