bonjour,
u0=50000
u1=uo+5000=50000+5000=55000
u2=u1+5000=50000+5000+5000=500000+2(5000)
suite arithmétique uo=50000 raison +5000
un=u0+n(5000)
v0=50000
v1=v0*1.07=50000x1.07
v2=v1x1.07=v0*1.07²
suite géométrique v0=5000 raison x1.07
vn=50000*1.07^n
u8=50000+8(5000)=50000+40000=90000
v8=50000 x 1.07^8=50000x1.71=85909
u8>v8
type 1 plus avantageux
u12=50000+12(5000)=50000+60000=110000
v12=50000x1.07^12=50000x 2.25=112609
v12>u12
type 2 plus avantageux
