Asymptotics of a 3F2 polynomial associated with the Catalan-Larcombe-French sequence

The large n behaviour of the hypergeometric polynomial $3F_2 (_{1over2 - n,1over2-n}^{-n,1over2,1over2};-1) is considered by using integral representations of this polynomial. This3F2 polynomial is associated with the Catalan-Larcombe-French sequence.Several other representations are mentioned, with references to the literature,and another asymptotic method is described by using a generatingfunction of the sequence. The results are similar to those obtained byClark (2004) who used a binomial sum for obtaining an asymptotic expansion.
