Answer:
First three terms of given sequence are
9, 13, 17
Step-by-step explanation:
By using subtraction of <em>yellow</em> areas from the <em>entire</em> squares, the areas of the <em>inscribed</em> shapes are listed below:
- 18 units
- 20 units
- 12 units
- 12 units
<h3>How to calculate the areas of the inscribed shapes</h3>
The areas of the <em>inscribed</em> shapes can be easily found by subtracting the <em>yellow</em> areas from the square, in order to find the value of <em>green</em> areas. Now we proceed to find the result for each case by using <em>area</em> formulae for triangles:
Case A
A = 6² - 0.5 · (3) · (6) - 0.5 · (3) · (6)
A = 36 - 18
A = 18 units
Case B
A = 6² - 4 · 0.5 · (2) · (4)
A = 36 - 16
A = 20 units
Case C
A = 6² - 0.5 · 6² - 0.5 · 6 · 2
A = 36 - 18 - 6
A = 12 units
Case D
A = 6² - 2 · 0.5 · 6 · 4
A = 36 - 24
A = 12 units

Answer:
1,572,861
Step-by-step explanation:
1. 3
2. 6
3. 12
4. 24
5. 48
6. 96
7. 192
8. 384
9. 768
10. 1536
11. 3072
12. 6144
13. 12288
14. 24576
15. 49152
16. 98304
17. 196608
18. 393216
19. 786432
Now we have to add all those
786432 + 393216 + 196608 + 98304 + 49152+ 24576 + 12288 + 6144 + 3072 + 1536 + 768 + 384 + 192 + 96 + 48 + 24 + 12 + 6 + 3..
This is alot of math but it equals 1572861
