David writes down the sequence 2,6,10,14 he says the sequence is n+4 is he correct

No.
Make this a table
X 1 2 3 4
Y 2 6 10 14
Plug in numbers into the equation.
1+4 = 5
or perhaps the third term
3+4 = 7 
doesnt work
He is incorrect. 

The correct equation would be
2+4n = y

If this helped please mark my answer as the brainliest
Thanks! 

He is incorrect, if the sequence was n+4 it would be 5,6,7,8. The only term that will be correct is the second term in the sequence, 6
