Answer 1

Guide, do not give direct answers please. :) Thanks.

Answer 2

Would you please photograph this problem and post the image here on Open Study. I thought about what you've typed and find the problem statement to be very ambiguous. Are you saying that k starts at 2 and ends at 9? or k starts at 2 and ends at 92? How am I supposed to know which is correct, or what you actually meant, if neither guess is correct?

Answer 3

its okay i just figured it out its D. I looked closely and the numbers were spread out. 9 end value. 2k sequence and k=2 is start value.

Answer 4

Great. Perhaps you could see for yourself what I meant by "ambiguous." Glad you have this problem straightened out!
