Given the explicit formula: a5= 8 + 7(n − 1)
What is the common difference?
What is the initial term?
What term is the formula finding?
What value should replace n?
A. 7
B. 8
C. 5
D. 6
The common difference is the coefficient of (n - 1), which in this case is 7. So the answer is A. 7.
The initial term is the constant term, which is 8. So the answer is B. 8.
The formula is finding term 5, which is represented by a5. So the answer is C. 5.
The value that should replace n is the position of the term we want to find. In this case, we are finding term 5, so n should be 5. So the answer is C. 5.
