Let X_(1), X_(2), X_(3)……. are in arithmetic progression with a common difference equal to d which is a two digit natural number. y_(1), y_(2), y_(3)……… are in geometric progression with common ratio equal to 16. Arithmetic mean of X_(1), X_(2)……..X_(n) is equal to the arithmetic mean of y_(1), y_(2)......y_(n) which is equal to 5. If the arithmetic mean of X_(6), X_(7)....X_(n+5) is equal to the arithmetic mean of y_(P+1), y_(P+2)......y_(P+n) then d is equal to
