Which of the following is an arithmetic sequence where a1 = 9 and d= 7? A) 0, 9, 18, 27, 36,...
B) 9, 16, 23, 30, 37, ...
C) 0,7, 14, 21, 28,..
OD 7, 16, 25, 34, 43,...

B.

Step-by-step explanation:

9 is the first term then we keep adding  common difference d = 7 to get the rest of the terms.

9, 9 + 7, 9 + 7 + 7,   and so on.

= 9, 16, 23, 30, 37

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

a c
