Answer:
its a)the first sequence is geometric bc of the common ratio of 2. the second sequence is arithmetic bc of the common difference of 7.
The first one is c because if you put it at negative 1/8 then it is 0-1/8 or 1/8 away from zero
second one is
the
reciprocal is the number that when multiiplied by the number you are
trying to find the reciprocal of, you get +1 so the number you have is
2/7 so
2/7 times x=+1
multiply both sdies by 7/2 to clear fraction
x=+7/2
the reciprocal is +7/2 or +3 and 1/2 which is D
2/9 • 3/4 • 2/5 = 1/15
