Answer:
199
Explanation:
For this problem, you have to write an formula.
a(n)=a(1)+(n-1)d
n is the term you are trying to find (in this case it's 50).
a(1) is the first term in the sequence (in this case it's 3).
d is the common difference (in this case it's 4).
Plug those in, and you get:
a(50)=3+(50-1)4
And you can easily solve that and get a(50)=199.
