<h3>
Answer: n^2 + 1</h3>
Explanation:
Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9
This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1
Let's do the math, 2.5+2.5+2.5+2.5( 4times) is 10hrs+2.5= 12.5hrs
Answer:
3000 minutes
Step-by-step explanation:
20 x 3 = 60 minutes
60 minutes = 1 hour
1 x 3 = 3km
3km = 1 hour
3 x 1000 = 3000 meters
Ans: 3000 meters
