It seems that the term increases 5 at a time, so (if this tendency continues) it's quite clear that the sequence is of the form 5n+k, for some constant "k". With a little experimentation, you can find that "k" should be 2.
t(n) = 12*n + 5
I suspect that the first term should be "negative 3", ie the sequence is -3, 1, 5, 9, 13, 17, ... The nth term is 4n - 7
7n - 4
The nth term is: 3n+2 and so the next number will be 20
Just subtract 9.
The nth term is 5n-3 and so the next term will be 22
5
tn=5n-3
It is: nth term = 35-9n
-11n + 17
The nth term is 25-4n and so the next term will be 5
t(n) = 12*n + 5
I suspect that the first term should be "negative 3", ie the sequence is -3, 1, 5, 9, 13, 17, ... The nth term is 4n - 7
7n - 4
It is 4n+5 and so the next term will be 25
The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.
The nth term is: 3n+2 and so the next number will be 20
