Answer:
A
Step-by-step explanation:
just cut off one side and add it to the other thats how you solve paralellograms
The nth term is 2n -1
1 and 3 lets say a1 and a2
common different = +2
Formula: nth term = dn + (a - d)
nth term = 2(n) + (1 - 2)
nth term = 2n + -1
nth term = 2n - 1
I hope this helps!
