First term → 6
Second term → (6*2+1) = 13
Third term → (13*2+2) = 28
Fourth term → (28*2+3) = 59
Fifth term → (59*2+4) = 122

    6×2+1=13
    13+1 ×2=28
    28×2+3=59
    59+1 ×2=120
    120×2+9=249
    249+1 ×2 =500
    500×2+27=1027..

    Just wondering how flexible and beautiful numbers are...
