Determine the following sequences whether ARITHMETIC or NOT
1) 10, 20, 30, 40,... = Arithmetic, the d(common diff) = 10
2)-16, -14, -12, -10,... = Arithmetic, d = 2
3) 1, -1, 1, -1,... = Not, the answer is 2 or -2
4) v/3, 2v/3, 3v/3, 4v/3,... = Arithmetic, cause when u subtract 2v/3 to v/3 u'll get this answer 1.7320508076
And the same answer if u subtract the others (3vl/3 - 2v/3) (4v/3 - 3v/3) same answer means arithmetic, btw that v/ symbol is actually squareroot but i dont have the real symbol so I improvise. And this is the last one,
5) 1/5, 1/7, 1/9, 1/11,... This I can't answer, Pls. Help me guys. Thank u.
