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.
What is the value of N?

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"
Life is about choices
is 2(4^7) = 4^9 ?parallel_chase wrote:Here is the answer

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...
