Answer:
See below
Step-by-step explanation:
<em>The question in full is attached</em>
The pond is 2 feet = 2*12 inches = 24 inch each side
Each side is 24/3 = 8 tiles long
<u>The first border line (yellow) has:</u>
- (8+1)*4 = 36 tiles
<u>The second line (green) has:</u>
- (9 + 1)*4 = 40 tiles and so on
Each following line has 4 more tiles
a) <u>As AP sequence it looks as:</u>
- 36, 40, 44, ..
So
- the first term = 36
- common difference = 4
b) Considering the alternating colors,
<u>Yellow sequence:</u>
- 36, 44, 52, ..
- The first term = 36
- Common difference = 8
<u>Green sequence:</u>
- 40, 48, 56 ..
- The first term = 40
- Common difference = 8
