Greets All, I'm having a little trouble in creating this example in mathematica, I'm not sure how to make the array dynamic enough in mathematica to include Cn.....Xn in example 1. Does anybody have any idea Example 1: User Input for four numbers 15,17,8,12... (Note: user can input any amount of numbers) (15+17) /25/2 ->b1 (b1+8) /25/2 ->b2 (b2+12) /25/2 ->b3 (b1+b2) /25/2 ->c1 (c1 +b3)/25/2 ->c2 (c1 +c2) /25/2 ->c3 Tia
