Answer:
505
Step-by-step explanation:
you first do 2020x2020 because you can see from the pattern, the inside squares are 1x1, 2x2, 3x3, so the 2020th inside squares would be 2020x2020. then, you would do 2020x4 for the shaded squares because if you see from the pattern, its 1x4, 2x4, 3x4, so the 2020th would be 2020x4. then you divide which is 505.
The "20" under <em>n</em> means "When <em>n</em> is 20,". Therefor, on the other side of the table, 5n-2 would be 5(20)-2. 5*20=100, 100-2 is 98. The top missing value is 98.
For the other side, it's saying that 5n-2 is 38. You have to work backwards to get your answer. The opposite of -2 is 2, so 38 + 2 is 40. The opposite of *5 is /5, so 40/5 is 8. The bottom missing value is 8.
