How to find out the nth term of a sequence

If i have this sequence;

3,5,7,9

And i wanted to find out the nth term...

I would;

find the difference between each number

5-3=2

then i would find out the previous term

so i would;

3-2=1

So the nth term of my sequence is;     2n+1

1 of 3

How would i find out the next term of my sequence?

If i had this nth term;

7n-4

And i wanted to know the first term, just substitute n for 1;

1 x 7=7
7-4=3

The first term is 3

If i wanted to know the 50th term

50 x 7= 350
350-4= 346
