In a list, between commas, or following a comma, a normal ellipsis is used, as in:

  
    
      
        1
        ,
        2
        ,
        3
        ,
        …
        ,
        100
      
    
    {\displaystyle 1,2,3,\ldots ,100}
  or to mean an infinite list, as:

  
    
      
        1
        ,
        2
        ,
        3
        ,
        …
      
    
    {\displaystyle 1,2,3,\ldots }
  To indicate the omission of values in a repeated operation, an ellipsis raised to the center of the line is used between two operation symbols or following the last operation symbol, as in:

  
    
      
        1
        +
        2
        +
        3
        +
        ⋯
        +
        100
      
    
    {\displaystyle 1+2+3+\cdots +100}
