Question Number 52221 by gunawan last updated on 04/Jan/19
a_n =(√(a_(n−1) +a_(n−2) ))  a_1 =1  a_2 =3  find explisit to a_n
$${a}_{{n}} =\sqrt{{a}_{{n}−\mathrm{1}} +{a}_{{n}−\mathrm{2}} } \\ $$$${a}_{\mathrm{1}} =\mathrm{1} \\ $$$${a}_{\mathrm{2}} =\mathrm{3} \\ $$$$\mathrm{find}\:\mathrm{explisit}\:\mathrm{to}\:{a}_{{n}} \\ $$
