a1 = √3 an+1 = √(3 + an) How do you prove that an is convergent? Would you find its limit by an tends to a (as n tends to inf.), so an+1 tends to a. Then solve for a by a2 = a + 3??

Prove that . Do this by induction. Then we know that an increasing bounded sequence converges. Then to find the limit solve this:
