Ineed to find a formula for r using r for the a) table and the b) table. any ?

A) R = (r + 3) + r*2

b) R = (r + 1) + (r*2 -1)

Notice the first sequence... notice how you get the next term, whatever the current one is, then you add 2 to it,  so.. that's your pattern



now, let's see the 2nd sequence, notice how you get the current term, by using the current term's ordinal value, square it, then add 1 to it, so, that's the pattern

What is the question?
