The following is an arithmetic sequence.
-3, 3, -3, 3
False
True and I wanna say false for this one am i correct?

Answer 1

Seems like there's a typo in " 1/2, 1/ 3/2, 2"

Answer 2

1/2, 1/ 3/2, 2 or 1/2, 1, 3/2, 2

Answer 3

see
1/2 +1/2 =1
1+1/2 = 3/2
3/2 +1/2 = 2
thus the common difference is 1/2 and constant so an arithmetic sequence..similarly can you check the second sequence you posted

Answer 4

in A.P the comman difference is same for all the terms. i.e \[a _{n}-a _{n-1} = d\] always , you can check by putting n=1,2,3,4 .......n any number what so ever. but remember here n represents the number of terms of series. and in your case the comman difference is 1/2.

Answer 5

it's supposed to be 1/2, 1, 3/2, 2

Answer 6

And? Subtract each successive pair and see what you get?

1 - 1/2 = ??
3/2 - 1 = ??
2 - 3/2 = ??

Answer 7

.5

Answer 8
