(35S) OEIS A157502, Evens Without Squares Formula - Gerald H - 12-07-2014 07:54 AM
Sequence of even numbers without the squares, OEIS A157502
2, 6, 8, 10, 12, 14, 18, 20, 22, 24, 26, 28, 30, 32, 34, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 66, 68…..
For index N solve the equation
G = IP( SQRT( 2 * N ) + 0.5 ) ► R + 2 * N – RMDR( R , 2 )
for G.
For input
N = 1E10
The calculator returns
G = 20,000,141,420
Anyone recognize 141,42……?
