This is a simple sequence question.
We can use the formula to figure this out:
Your starting term is 3 and the pattern is adding 4.
To find the 7th term just replace the n in the formula with 7.
We get: 3+4*6 = 27
Your seventh term is 27!
We can also count by 4's just to check:
3, 7, 11, 15, 19, 23, 27.
ANSWER: 27
