It is: nth term = 29-7n

The nth term is -7n+29 and so the next term will be -6

The nth term is: 2n+7 and so the next number will be 19

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.
