Answer 1

A sequence is Arithmetic, when you have a common difference between the terms.

so, Arithmetic sequence will have:

2nd term - 1st term = 3rd term -2nd term = 4th term -3rd term and so on....

Answer 2

so what you consider it would be because I have no clue on this problem. ?

Answer 3

i just gave you a clue!
say i take
–4, –2, 0, 2, …

1st term = -4
2nd term = -2
3rd term = 0
and so on

so for this sequence, is this true ??
2nd term - 1st term = 3rd term -2nd term = 4th term -3rd term and so on....

Answer 4

Answer 8

could you find any pattern in that sequence ??

like if you add some number, you get the next number ?

Answer 9

+10 from16 will get to your 5th sequence

Answer 10

6+... = 11
11+...=16
?

Answer 11

16, ____ 26 16+10 will equal your 5th sequence but now I gotta figure out the 4th one now

Answer 12

6+"5" = 11
11+"5"=16

so 16+5 will give you next number,
and 26+5 will give you the last

plug in d= 3
a_n =36, n =12
only a1 is unknown :)
