This paper considers the relevance of the quasi-de Sitter solution for the modified 𝐹(𝑇, (∇𝑇)2) teleparallel theory of gravity. The Hubble parameter is represented in the form: = 𝐻* + 𝜖𝑒-𝐵𝑡, where 𝐻*,𝐵 - 𝑐𝑜𝑛𝑠𝑡. The cosmological equations of the model with a perfect fluid are written for the following choice of function 𝐹: = 𝐴𝑇𝑛+𝜔(𝑇)∇𝜇𝑇∇𝜇𝑇. The evolution of matter density perturbations in the absence of pressure perturbations is considered.
