Answer 1

30,a) A = { 15,17,19,21,23}
   B = { 17,15,21,19,23}
   C = { 23.21.19.17.15}

b) A = {3,6,9,12,15,18,21,24,27,30}
    B = { 9,6,3,12,15,18,21,24,27,30]
     C = { 30,27,24,21,18,15,12,9,6,3}

c)  A = [64,81,100,121,144,169,196]
     B = { 8²,9²,10²,11²,12²,13²,14²}
     C = { 196,169,144,121,100,81,64}
