There is no such equation.

The given points give us 3 equations:

(1) 2+=+b%5E%28k-2%29
(2) 3+=+b%5Ek
(3) 6+=+b%5E%28k%2B1%29

Equations (1) and (2) together give us

b%5Ek%2Fb%5E%28k-2%29+=+b%5E2+=+3%2F2 --> b+=+sqrt%283%2F2%29

Equations (2) and (3) together give us

b%5E%28k%2B1%29%2Fb%5Ek+=+b+=+2
