The sequence is Un = 19 - 3n so the 20th term is 19 - 3*20 = 19 - 60 = -41
taking the 1st term as n=1 the 2nd term as n= 2 etc then the first 5 terms of 16-3n are : 1st : 16-3 = 13 2nd : 16-6 = 10 3rd : 16-9 = 7 4th: 16-12 = 4 5th : 16-15 = 1 hope this helps

It is: 3n+1
75988 to the 7th
2n+1
+3
The nth term is 3n+7 and so the next number will be 22
The nth term is: 3n+1 and so the next number will be 16
Tn = 1 + 3n
3n+7

Domain includes all of the x-coordinates, which are 10, 14, 4, 13, -16, and 17. So the domain would be the set {-16, 4, 10, 13, 14, 17}
