Alright, let’s break it down:

- Here’s the series: 10, 34, 66, 108, 162, ?

- Let’s look at the differences between the numbers:

- 34 - 10 = 24

- 66 - 34 = 32

- 108 - 66 = 42

- 162 - 108 = 54

- Now, check how these differences are changing:

- 24, 32, 42, 54

- Difference between them: 8, 10, 12

- So, each time the difference goes up by 2 more than before.

- Let’s continue: next difference should be 54 + (12 + 2) = 54 + 14 = 68

- Now, add 68 to 162: 162 + 68 = 230

So, here’s what this really means: the answer is 230.

Option 4: 230
