Tom reads 2 pages on Monday, 6 pages on Tuesday, 18 pages on Wednesday, and 54 pages on Thursday. If this pattern continues, how many pages will he read on Friday?

The number of pages read each day is:
Monday: 2 pages
Tuesday: 6 pages
Wednesday: 18 pages
Thursday: 54 pages

Let's find the ratio between consecutive days:

$$\frac{\text{Pages on Tuesday}}{\text{Pages on Monday}} = \frac{6}{2} = 3$$ $$\frac{\text{Pages on Wednesday}}{\text{Pages on Tuesday}} = \frac{18}{6} = 3$$ $$\frac{\text{Pages on Thursday}}{\text{Pages on Wednesday}} = \frac{54}{18} = 3$$

The pattern shows that Tom reads 3 times the number of pages he read the previous day.

Following the pattern, the number of pages Tom will read on Friday will be 3 times the number of pages he read on Thursday.

$$\text{Pages on Friday} = 54 \times 3 = 162$$

If this pattern continues, Tom will read $\boxed{\text{162}}$ pages.
