**Abstract: **
| The purpose of this paper is the study of the growth of solutions of higher order linear differential equations f(k) + (Dkâˆ’1 + Bkâˆ’1eQkâˆ’1(z))f(kâˆ’1) + Â· Â· Â· + (D1 + B1eQ1(z)) fâ€² + (D0 + A1eP1(z) + A2eP2(z)) f = 0, where Ai(z) (Ì¸â‰¡ 0) (i = 1, 2), Bj(z) (Ì¸â‰¡ 0) (j = 1, ..., k âˆ’ 1), Dm (z) (m = 0, ..., kâˆ’1) are meromorphic functions of finite order less than n, Pi (z) = ai,nzn+Â· Â· Â·+ai,0 and Qj (z) = bj,nzn+Â· Â· Â·+bj,0 are polynomials with degree n â‰¥ 1 such that ai,q, bj,q (i = 1, 2; j = 1, ..., k âˆ’1; q = 0, 1, ..., n) are complex numbers. Our results extend the previous results due to Habib and BelaÂ¨Ä±di [3], [11], [12] and Beddani and Hamani [4]. |
