Abstract
The delay integro-differential equation for the Volterra type has
been solved by using the two-point multistep block (2PBM) method with constant
step-size. The proposed block method of order three is formulated using Taylor
expansion and will simultaneously approximate the numerical solution at two
points. The 2PBM method is developed by combining the predictor and corrector
formulae in the PECE mode. The predictor formulae are explicit, while the
corrector formulae are implicit. The algorithm for the approximate solutions
were constructed and analyzed using the 2PBM method
with Newton-Cotes quadrature rules. This paper focused on constant and
pantograph delay types, and the previous values are used to interpolate the
delay solutions. Moreover, the studies also carried out on the stability
analysis of the proposed method. Some numerical results are tested to validate
the competency of the multistep block method with quadrature rule approach.

Abstrak
Persamaan pembezaan lengah kamilan bagi jenis Volterra telah diselesaikan menggunakan kaedah blok berbilang langkah dua titik (2PBM) untuk langkah yang malar. Kaedah blok peringkat tiga yang dicadangkan telah dirumus menggunakan pengembangan Taylor dan akan menganggar penyelesaian berangka secara serentak pada dua titik. Kaedah 2PBM dibangunkan dengan menggabungkan formula peramal dan pembetul dalam mod PECE. Kaedah peramal adalah tak tersirat manakala kaedah pembetul adalah tersirat. Algoritma penyelesaian anggaran dibina dan dianalisis menggunakan kaedah 2PBM dengan peraturan kuadratur Newton-Cotes. Kertas ini memberi tumpuan kepada jenis kelengahan malar dan pantograf serta nilai sebelumnya digunakan untuk menginterpolasi penyelesaian kelengahan. Selain itu, kajian juga dijalankan ke atas analisis kestabilan bagi kaedah yang dicadangkan. Beberapa keputusan berangka diuji untuk mengesahkan kecekapan kaedah blok berbilang langkah dengan pendekatan peraturan kuadratur.
Kata kunci: Blok berbilang langkah; peraturan Newton-Cotes; persamaan pembezaaan lengah-kamilan Volterra
