Best ResponseYou've already chosen the best response.0well, we know the 13th term is 59 and the 1st one is 13 so, we could say that \(\bf a_{\color{brown}{ 13}}={\color{blue}{ a_1}}+({\color{brown}{ 13}}1)d\implies 59={\color{blue}{ 13}}+({\color{brown}{ 13}}1)d\) so, to find "d", just solve for "d" :)

Best ResponseYou've already chosen the best response.0once you find "d", you can find \(\Large a_{32}\)

Best ResponseYou've already chosen the best response.0hmmm actually is 59 but anyhow \(\bf a_{\color{brown}{ 13}}={\color{blue}{ a_1}}+({\color{brown}{ 13}}1)d\implies 59={\color{blue}{ 13}}+({\color{brown}{ 13}}1)d\)

Best ResponseYou've already chosen the best response.0\(\bf a_{\color{brown}{ 13}}={\color{blue}{ a_1}}+({\color{brown}{ 13}}1)d\implies 59={\color{blue}{ 13}}+({\color{brown}{ 13}}1)d \\ \quad \\ 5913=12d\implies 72=12d\implies \cfrac{\cancel{72}}{\cancel{12}}=d \\ \quad \\ 6=d\)
