Answer: Only the second sequence is arithmetic.
Work:
An arithmetic sequence is a sequence in which there is a common value added or subtracted between each term in the sequence.
The first option, -2, 4, -6, 8,... is not arithmetic because the terms switch back and forth between positive and negative signs meaning that there is no common value that can be added between each term.
The second option, -8, -6, -4, -2,... is arithmetic because there is a common difference between each term which is +2.
The third option, 2, 4, 8, 16,... is not arithmetic but is, in fact, geometric. There is no common value that is added or subtracted between each term.
Answer:
1 and 13/24
Step-by-step explanation:
you find a common denominator which is 24 then convert both to that number which gets you to
22/24 and 15/24
then you add 22 and 15 to get 37,
which you then make it into a mixed number by subtracting 24 from 37 to get 13/24 and you add your 1
to get 1 and 13/24 as your answer of how far Brock had walked on Mondat and Tuesday.
