please help (multiple choice)
i believe this is not even arithmetic
well…because if you add 1/6 each time… no, this must be geometric
Yes, you add 1/6 to each preceding term. Hence, 1/6 is the common difference.
@Jamierox4ev3r I don't mean to correct you but, it is an arithmetic sequence because an arithmetic sequence goes from one term to the next by always adding (or subtracting) the same value. For instance, 2, 5, 8, 11, 14,... and 7, 3, –1, –5,... are arithmetic, since you add 3 and subtract 4, respectively, at each step. A geometric sequence goes from one term to the next by always multiplying (or dividing) by the same value. So 1, 2, 4, 8, 16,... and 81, 27, 9, 3, 1, 1/3,... are geometric, since you multiply by 2 and divide by 3, respectively, at each step.
but…it turns into 1 1/3 and then 1 1/2
hmmm its been a while since I've done these >.< god dang it memory of mine, WORK!
oh wait… *facepalm*
what was i thinking? yeah i knew that B is correct
for some reason, i thought multiplication was happening so i thought it was geometric
B is correct and 1 1/3 + 1/6 = 1 1/2
the error of my thinking could possibly be my folly/hamartia. I am an imperfect human being :P
It would not be an arithmetic progression: 1, 1(1/6), 1(1/3), 1(1/2) Add 1/6 to the first to get the second, you add 1/6 again to get the third because 2/6 simplifies to 1/3. You then add 1/6 to 2/6 to get 3/6 which simplifies to 1/2. Therefore it's an AP
Sorry, would :P
I did what Jamierox did at first
lol my mistakes are infectious
