Below is a pyramid, with different numbers in each cell: 198, 263, 431, 265, 446, 679, 681, 1110. However, two cells contain the letters E and D.
Your task is to use your intelligence to find the values of the two letters E and D accurately, following the pattern of the numbered cells.
What are the values of E and D?
Finding the answer is not simple at all; hidden within the numbered boxes are extremely complex underlying patterns. Think carefully, discover the pattern of the numbers, and choose the appropriate digits. Hint: The values of E and D consist of 4 digits and are less than 2,500.
The hint has been given; use your skills and intelligence to find the correct answer.
