tell whether the sequence 1/3, 0, 1, -2.... is arithmetic, geometric, or neither. find the next three terms o the sequence.
u sure
does it follow any properties for arith or geo?
no
how can we chk if it does or not tho?
I AM NOT SURE
an arith seq has the same number added to each term to get the next one. your first term is: 1/3 your second term is: 0 1/3 + d = 0 what would d have to be in this case?
0
1/3 + 0 does not equal 0
OK SORRY
1/3 + d = 0 ; solve for d by subtracting 1/3 from each side -1/3 -1/3 ------------- d = -1/3
now that we should have a proper "d", lets see if it fits 0 + d = 1 0 - 1/3 = 1 is false; so this cant be an arith seq can it
SO ITS NOT GOING TO BE THAT THE U HAVE TO SEE IF ANYTHIG MULTIPLYS FOR GEOMETRIC
correct 1/3 * d = 0 ; only when d=0 0 * r = 1 , well, never .... so it doesnt hold to a geo seq either
SO ITS NOT GOING TO BE THAT I ALREADY TRIED THAT SO THE ANSWER IS NEITHER
THANKS SOMUCH FOR SHOWING ME THAT
youre welcome, and good luck :)
