The journal retracts the paper entitled "Qualitative analysis of coupled system of sequential fractional integrodifferential equations" ^[1]. This article is very similar to A. Wongcharoen, et al. "Existence Results for a Nonlocal Coupled System of Sequential Fractional Differential Equations Involving $\psi$ -Hilfer Fractional Derivatives" ^[2]. In accordance with our publishing policies, an investigation was conducted that confirmed the overlap. The article ^[1] is therefore retracted and shall be marked accordingly.

This retraction was approved by the Editor in Chief of the journal AIMS Mathematics.

The authors agreed to this retraction.
