@Suvra Saurav
I think may be 96 is 196.
Because 196- 14^2.
169- 13^2
144- 12^2
121- 11^2
And there is "101" wrong number.

It can also be done as:
A, (A+1)X1, (B+1)X2, (C+1)X3, (D+1)X4, (E+1)X5, (F+1)X6.
i.e.,
A = 7.
B = (7+1)X1 = 8.
C = (8+1)X2 = 18.
D = (18+1)X3 = 57.
E = (57+1)X4 = 232.
F = (232+1)X5 = 1165.
A, (A+1)X1, (B+1)X2, (C+1)X3, (D+1)X4, (E+1)X5, (F+1)X6.
i.e.,
A = 7.
B = (7+1)X1 = 8.
C = (8+1)X2 = 18.
D = (18+1)X3 = 57.
E = (57+1)X4 = 232.
F = (232+1)X5 = 1165.
