a = (a+d)+4
(a+d)+(a+2d) = "2 by 2/3" (whatever that means)
Anyway, now just solve for a and d, and then list the first 4 terms.
Help me this. The first term of the GP exceeds the second term by 4 and the sum of the second and third terms is 2 by 2/3.Find the first four terms?

Oops. I worked an A.P., not G.P.
a = ar + 4
ar + ar^2 = "2 by 2/3"
Now just solve for a and r and then list the first 4 terms.
a = ar + 4
ar + ar^2 = "2 by 2/3"
Now just solve for a and r and then list the first 4 terms.
2 by 2/3
---> old way of saying 2 divided by 2/3
as in 12 รท 3 or 12 by 3
(don' know why they didn't just say 3)
