Answer:
See below.
Step-by-step explanation:
Alexi originally has $43 in his bank account and deposits $7 per week.
Week 1: $50
Week 2: $57
Week 3: $64
Week 4: $71
Week 5: $78
The pattern is that it increased $7 every week starting from $43.
A pattern rule would be: y = 7x + 43 where x represents the number of weeks.
We have that the fourth term of an arithmetic sequence is
a_4=14
Option C
From the question we are told
What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?
A) 78
B) 32
C) 14
(Explain your work)
Generally the equation for the arithmetic sequence is mathematically given as

Therefore
For seventh term

Therefore
For Fourth term

a_4=14

Thats 3.85714285714 because if you add the numbers and divide by the numbers they are it’ll be 3.85714285714
Answer:
Part A:

Part B:

Step-by-step explanation:
The total number of candies is 40.
10 + 14 + 4 + 12 = 40
14 are Butterfinger and 12 are Crunch.
14 + 12 = 26



40 - 1 = 39

× 

2x+2y =50
2(7)+ 2(3)=50
14+6 =50
20=/=50
This is false because when you substitute the variables with their numbers and then multiply and add, your answer does not equal 50
