Answer:
6
Step-by-step explanation:
Multiply all three sides by 8 to get x by itself
16/3 < x < 7
5 1/3 < x < 7
so it’s between 5 and 1/3 and 7. the only answer between those two would be 6. 3 and 4 is too less. 5 is also too less.
Answer:
an = 1/4(8)^n-1
Step-by-step explanation:
Given the following in a geometric sequence, a2=2, a3=16, and a4=128.
nth term of a sequence = ar^n-1
a is the first term
r is the common ratio
r = a3/a2 = a4/a3
r = 16/2 = 128/16
r = 8
a2 = ar
2 = 8a
a = 2/8
a = 1/4
The nth term by substituting the parameters will be;
an = 1/4(8)^n-1
Answer:
Hi how are you doing today Jasmine
The ratio is 4/3 because you add AC which is 12 and then divided 9 (BC) by 12
