Arithematic Sequences

Which sequence is an Arithmetic Sequence ?

• 3,4,5,7,11.......

• 16,13,10,7,............

• 5,3,1,0,-1........

• 0,1,2,3,7........

The set which obeys a certain rule is call A SEQUENCE
A  { 2, 5, 8, 11,.........}
B {  2, 5 ,6, 10, 39,...}
which one is the sequence

• A
• B

   2, 5, 8, 11,.......find the common difference (d)

• 3
• -3
