$4n-1$ for the first term put $n=1$ and get 
$$4\times 1-1=4-1=3$$

anonymous · Answer

Basically, to create this sequence, you'll take the rule and plug in n=1, then n=2, then n=3, and so on. We only want the first three though.

anonymous · Answer

for the second term, put $n=2$ and get 
$$4\times 2-1=8-1=7$$

anonymous · Answer

and for the third term put $n=3$ and  see what you get
