Given that the sequence {an}, Sn is the sum of the first n terms, satisfying the relation 2Sn = 3an-3, the general term formula of {an} can be obtained

Given that the sequence {an}, Sn is the sum of the first n terms, satisfying the relation 2Sn = 3an-3, the general term formula of {an} can be obtained

2Sn=3an-3, 2S(n-1) = 3a(n-1) -3
Difference: 2 [Sn - S (n-1)] = 3an - 3A (n-1)
2an = 3an -3a(n-1)
an = 3a(n-1)
an/ a(n-1) =3
The sequence {an} is an equal ratio sequence, and the formula is 3,
When n = 1, A1 = 3a1-3, A1 = 3 / 2
an= (3/2)* 3^(n-1) = 3^n/2
