Answer:
The nth term is 2n - 1 .
Step-by-step explanation:
You have to apply arithmetric formula, an = a + (n-1)d where a represents first term, n is nth term and d is common difference :
[tex]an = a + (n - 1)d[/tex]
[tex]let \: a = 1,d = 2[/tex]
[tex]an = 1 + (n - 1)(2)[/tex]
[tex]an = 1 + 2n - 2[/tex]
[tex]an = 2n - 1[/tex]
