Use the arthimetis sequence of numbers 1,3,5,7,9,... to find the following what is d, the difference between any 2 terms? show work 

 

              

        d = 3 - 1 

          = 2              



Using the formula for the nth term of an arthimetoc sequence, what is the 101st term? show work? 





   d = 2

   n = 101

            

            

            

            

            



Using the formula for the sum of an arthimetic sequence, what is the sum of the first 20 terms? show work 





   d = 2

   n = 20

                    n

             = ___ 

                    2

            

Let us find  first: 

            

            

            

            

            





                    20

             = ___ 

                    2



                         

             =  10 (40)

                       = 400                                   



            



Using the formula for the sum of an arthimetic sequence, what is the sum of the first 30 terms? show work





   d = 2

   n = 30

                    n

             = ___ 

                    2

            

Let us find  first: 

            

            

            

            

            





                    30

             = ___ 

                    2



                         

             =  15 (60)

                       =  900
