------l------l------l------l------l------ 4^7 is the first segment. 4^9 is the second segment. And N is the forth segment. what is the value of N? (All the segments are same distance) answer [spoiler]3(4^9)-2(4^7)[/spoiler] explanation needed.

I'm confused. I can see how OA can be correct, but can the answer also be 4^9 + 4^9?

Which exactly is the first segment, the second, the third and the fourth? Thanks.

------l 4^7 ------l------l 4^9 ------l------l------l------l N i am also confused with answer.

Here is the answer We know that all the segments are equal. therefore each segment will be = 4^9 - 4^7 first = 4^7 second = 4^9 third = 4^9 + (4^9 - 4^7) fourth = 4^9 + (4^9 - 4^7) + (4^9 - 4^7) = 3(4^9) - 2(4^7) Hope this helps.

AGREE...I've the same answer by the same calculation with "parallel_chase"

I think the problem is not stated correctly 4^7 is the first segment this is AT MOST one point in a line / segment, and a point is NOT a segment. 4^9 is the second segment. same as above

I think it would be much easier to state it as 4^9 + 4^9 IMO.... but it's kind of hard to tell w/o any multiple choices...

thanks parallel chase. difficult problem simple solution
