Use an incrementing variable in conjunction with the member function to check the variable against a list of numbers, e.g.:

(defun missingnumbers ( l / i m r )
   (setq i (apply 'max l)
         m (apply 'min l)
   )
   (while (< m (setq i (1- i)))
       (if (not (member i l)) (setq r (cons i r)))
   )
   r
)

_$ (missingnumbers '(1 2 3 5 68 99))
(4 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98)

_$ (missingnumbers '(350 351 352 355 386))
(353 354 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385)
