For each positive integer n, the quantity \(s_{n}\) is defined such that \(s_{n + 2} = (s_{n})^2 − s_{n + 1}\). In addition, \(s_{2} = 1\).
Select values for \(s_{1}\) and \(s_{4}\) that are jointly compatible with these conditions. Make only two selections, one in each column.

Given: sn+2=(sn)2−sn+1
S2 = 1.
When we substitute values for S3 and S4 we get:
S3 = S1^2 - S2.
S4 = S2^1 - S3 => S4 = S2^1 - S1^2 + S2,
Now Substituting S2 =1, we get:
S4 + S1^2 = 2.
Only 2 values satisfy the given condition: S4 = -7, S1 = -3
S2 = 1.
