If i have this sequence;


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

find the difference between each number


then i would find out the previous term

so i would;


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;


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

1 x 7=7

The first term is 3

If i wanted to know the 50th term

50 x 7= 350
