I researched and found this question:
"In a series of 33 pearls, the pearl in the center of the largest and
expensive of all. At one end of each pearl is worth
£ 100 more than the last one in the middle. On the other
End, each pearl is 150 pounds more than the previous, until
means. The necklace is worth £ 65,000. What is the value
Pearl of the Orient? "
Solution:
There are exactly 16 balls on the side of good in the Pearl
Center. Let us assume that the value of the pearl in the center x. £
Add pairs of beads, with the formula of the proposed
Problem:
.......... x
......../... \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\
(x-100) .. (x-150) ← 2x-250
.......|......|
(x-200) .. (x-300) ← 2x-500
.......|......|
(x 300) .. (x-450) ← 2x-750
.......|......|
(x 400) .. (x-600) ← 2x-1000
.......|......|
.......|......|
.......|......|
(x-100N) .. (x-150N) ← 2x-250N
Add to have them all, we:
Value = x + n (2x) - (250 + 500 750 ...250 N) = (2n +1) x - 250 (n (n +1)) / 2
In this case, we have 16 balls on each side, if n = 16, and the total value of £ 65,000.
65000 = (2 * 16 + 1) x - 250 (16 * 17 / 2)
65,000 = 33x - 34000
99,000 = 33x
x = 3000
which the value of € 3000 for the center bead is.
I agree with the answer, what are you talking about?
