If I understood your interpretation of the problem correctly the integers chosen for TASK I would be as you posted in your solution, yet I can find a smaller total sum for both TASK II and TASK III.

TASK I:   SUM   DIFF  PROD  QUOT
 1  2  3   3[O] 1[O]   2[E]   2
 3  6  9   9[O] 3[O]  18[E]   2
 5 10 15  15[O] 5[O]  50[E]   2
 7 14 21  21[O] 7[O]  98[E]   2
     ---
      48

TASK II:  SUM   DIFF   PROD  QUOT
 2 14 16  16[E] 12[E]  28[E]   7
 4  8 12  12[E]  4[E]  32[E]   2
 6 12 18  18[E]  6[E]  72[E]   2
10 20 30  30[E] 10[E] 200[E]   2
     ---
      76 <-- a smaller sum by 2

TASK III:  SUM   DIFF  PROD   QUOT
 1 11 12   12[E] 10[E]  11[O]  11
 5 15 20   20[E] 10[E]  75[O]   3
 7 21 28   28[E] 14[E] 147[O]   3
 3  9 12   12[E]  6[E]  27[O]   3
     ---
      72  <-- a smaller sum by 16
