  Let $(A, \m, k)$ be a Gorenstein local ring of dimension $ d\geq 1.$ Let $I$
be an ideal of $A$ with $\htt(I) \geq d-1.$
  We prove that the numerical function \[ n \mapsto \ell(\ext_A^i(k,
A/I^{n+1}))\] is given by a polynomial of degree $d-1 $ in the case when $ i
\geq d+1 $ and $\curv(I^n) > 1$ for all $n \geq 1.$
  We prove a similar result for the numerical function \[ n \mapsto
\ell(\Tor_i^A(k, A/I^{n+1}))\] under the assumption that $A$ is a \CM ~ local
ring.
  \noindent We note that there are many examples of ideals satisfying the
condition $\curv(I^n) > 1,$ for all $ n \geq 1.$
  We also consider more general functions $n \mapsto \ell(\Tor_i^A(M,
  A/I_n)$ for a filtration $\{I_n \}$ of ideals in $A.$ We prove similar
results in the case when $M$ is a maximal \CM ~ $A$-module and
$\{I_n=\overline{I^n} \}$ is the integral closure filtration, $I$ an
$\m$-primary ideal in $A.$
