You Have to use the Formula of:
dn + (a-d).
d= The difference in the sequence
n= Stays how it is
a= The first number in the Sequence.
For Example: 4, 7, 10, 13, 16
3n + (4-3)
So the answer is: 3n + 1

The nth term is Un = a + (n-1)*d where a = U1 is the first term, and d is the common difference.
Say if you had the pattern 15 20 25 30 35 40 45 50 To find the nth term you have to see what the gap between the numbers is. In our case this is 5. Then you have to find out what the difference between the gap and the first number. In this sequence it is 10. So your answer would be..... 5n+10 That's how you find the nth term.
i dont get it
123456789 * * * * * The nth term is 3n
