Mr. moore read 25 pages of a book on monday. he reda 32 pages on tuesday, 39 pgs on wensday, and 46 pgs on thursday. if this pattern continues how many pages will mr. moore read on sunday?

It's increasing by 7 each time so by Friday it will be 53. Saturday, 60. And Sunday 67.

So he will read 67 pages on Sunday. 

Okay. So if you solve for the difference, the common difference is 7. Monday is first in the pattern and there are 7 days in one week. Sunday makes the 7th day. The formula for finding patterns is an = a1 + (n - 1)d, where n is the number term we are looking for and d is the difference.  7 is the term we are looking for. 7 - 1 is 6. 6 * 7 is 42. Now, we can add 25, which is the first term in the sequence. 42 + 25 is 67. There. Mr. Moore will read 67 pages on Sunday.
