We present Binet’s formulas, generating functions, Simson formulas, and the summation formulas for these sequences. Moreover, we give some identities and matrices related with these sequences.</p&gt;}, number={2}, journal={Earthline Journal of Mathematical Sciences}, author={Soykan, Yüksel}, year={2020}, month={Oct.}, pages={297-327} }
