The variance of 14 14 20 38 47 48 57 = 317.6667
20 + 18 = 38
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40
No because they are composite numbers with more than two factors
1 and 2
if U0=40 U1=38=40-2 U2=34=38-4 U3=28=34-6 xn+1=xn-2*n and the next numbers are 20 and 10
20 + 18 = 38
38
It is 20 because 18+20 = 38

How about 6, 12 and 20?
6, 12, and 20
No because they are composite numbers with more than two factors
