Which of the following sequences of numbers are arithmetic sequences?

check all that apply.

a. -3, -11, -17, -23, -33,
b. 3, 10, 17, 24, 31,
c. 1, -2, 3, -4, 5,
d. 45, 46, 47, 48, 49,
e. 54, 71, 88, 105, 122,

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.

hand, ambitous, ace, genius.
