Determine the tenth number in each number pattern:

a) 12,3,-6....

b) -18,-7,4...

is there any other way to get the 10th term rather than just keep going till i reach the 10th number?

thankies :)

Try

is the first term.

d=common difference.

n=the nth term you want

Try #1 for the 10th term:

Now, try the 2nd one yourself. OK?. - December 20th 2006, 04:50 PMpuppy_wish
