2nd one - y = 3/7x + 6 , hope this helps:)
Answer:
the first term is a1
the distance between the numbers is d
we have:
a5 = a1 + 4d = 23
a12 = a1 + 11d = 72
so we have the equation:
a1 + 4d = 23
a1 + 11d = 72
=> a1 = -5
d = 7
=> an = -5 + 7(n - 1) = 7n - 12
with an = 7n - 12
=> a2 = 2
a3 = 9
so the first three terms is -5; 2; 9
Answer:
C
Step-by-step explanation:
i am smart
2/5 or 0.4 Because only two of the five numbers are even or greater than 78
I would say C 9 because the only term with a 9 in it is 9f4g
