19 - 3n
123456789 * * * * * The nth term is 3n
Just plug in 30 for n in 3n-1. The answer is 89.
The nth term is 4n-1 and so the next term will be 19
It is: nth term = 7n-9
nth term is n squared plus three
123456789 * * * * * The nth term is 3n
3n+7
The nth term is 3n+7 and so the next number will be 22
The nth term is 2 + 3n.
The nth term is 3n+2 and so the next number will be 17
3n +5
3n(n+1] + 5 is the nth term
The nth term of this sequence is 3n + 4
3,6,9,12.....
3n
3n
Just plug in 30 for n in 3n-1. The answer is 89.
