The arithmetic sequence with the given condition is determined recursively by
So we have
and so on with the general pattern
This means the 72nd term in the sequence is
so the answer is B.
The property of equality of the rows, columns, and diagonals in the magic
square can be used to find the value of <em>n</em>.
The value of <em>n</em> is 6
Reasons:
The magic square can be presented as follows;
Given that the sum of the numbers in each row and in each column and in
each of the two diagonals are equal, to find the value of <em>n</em>, two rows having
different number of the variable <em>n</em> can be equated as follows;
The top row = n - 2 + 3 + n + 2 = The bottom row = 2 + 2·n - 5 + n
n - 2 + 3 + n + 2 = 2 + 2·n - 5 + n
2·n + 3 = 3·n - 3
3·n - 3 = 2·n + 3 (symmetric property)
3·n - 2·n = 3 + 3
n = 6
