I know how to do all the geometric and arethmatic formulae, but i just can't work out the first 4 terms from that formula given. Any suggestions?
Hmmm, lessee now ..... If we let r = 1, the rule tells us that $\displaystyle a_{2} = a_1 + 3$. But holy cow ...... $\displaystyle a_1 = 4$. So $\displaystyle a_2 = 7$. Hmmmmm ..... can you play this game when r = 2? r = 3?

The answer book says its 4 , 7 , 10 , 13
Which is obviously + 3, but i dont understand how the formula shows that exactly.
I can see how the first one is 4, as it says $\displaystyle a_1 = 4$, but i cant see how it shows + 3.

$\displaystyle a_{r+1} = a_r$ + 3. Translation: The next term is 3 more than the previous term. That's what the + 3 in the given rule means!!! What do you think the + 3 means?
