Answer:
11
Step-by-step explanation:
We have been given that tiles in each new row is 2 less than the row below it and the first roe has 23 tiles.
We can see that tiles in rows represents a arithmetic sequence. So we will use arithmetic sequence formula to find the number of tiles in 7th row.
, where is nth term of sequence, is first term of sequence and d is the common difference between consecutive terms.
Let us substitute our given values in above mentioned formula to find the 7th term of our arithmetic sequence.
Therefore, there will be 11 tiles in 7th row.

A is the quickest way to do the problem.
1)3/5
2)7/20
3) 7/5
