Answer:
A= 2(n-1)+3
Step-by-step explanation:
We can see by the pattern by counting the number of line segments that we get a sequence of:
3, 5, 7...
From this, we can derive a pattern:
We know that when n=1, A=3. When n=2, A=5. When n=3, A=7
From substituting values, we can get a pattern of:
A= 2n+1
