The pattern is +a%5Bn%5D+=+5n+-+4+ , n = 1,2,3, …
+a%5B1%5D+=+1+
+a%5B50%5D+=+246+
+a%5B51%5D+=+251+ <<<—— first number on page 2

Page number = floor ( n / 50 ) + 1 where floor(x) means truncate x to the closest integer less than or equal to x.

…..
+a%5Bn%5D+=+5n+-+4+=+12346+
+5n+=+12350+
+++n+=+2470+
Page = floor( 2470/50 ) + 1 = floor (49.4) + 1 = 49 + 1 = 50

Ans: Page 50 will have the number 12346.
