The answer if we go by solving only for "r" Will be -2, in other words r=-2
Answer:
4
Step-by-step explanation:
30 + 20 + 13 = 63, + fractions = 64. But you have to divide to get to pounds. So 64 / 16 = 4
YAY
Answer:

Answer:
The first term of the sequence is 1/5
Step-by-step explanation:
The first term is 1/5.
The reason is that there is a common ratio between each term. In this case multiplying the previous term in the sequence by 5 would give the next term.
So in this case 1/5 is the first term.
If we multiply 1/5 by 5, it will give the next term which is 1.
1/5*5=1
Thus the first term in the sequence = 1/5....
14, finding the rate of change is simple,
142-128 = 14
156-142 = 14
170-156 = 14
184-170 = 14
14+14+14+14 = 56
There are 4 integers so divide by 4
56/4 = 14
so the answer is 14
