Find the common difference of the arithmetic sequence 11,34,57,80,......
good, then youve found your common difference of your arithmetic sequence
so thats the answer? Im having a hard time with sequencing
thats it. each term differs from the next by a common value of 23
if youve ever learned your multiplication tables; then youve done arithmetic sequencing already.
if you want the formula for common difference..it's A_n - A_(n-1) so lez say you pick A2 which is 34..subtract A_1 which is 11 from that.. @amistre64 if only fool's arithmetic progression were like these huh? common differences..
3,6,9,12,15,... 4,8,12,16,20,32, ... thats all it is; except for a "shift" sometimes
