\(\sqrt{2} \approx 1.4\), thus the sum of two consecutive terms of the sequence \(\approx 1.4 - 2 = -0.6\).

Since its mentioned in the question all odd numbered terms are equal and all even numbered terms are equal.
All odd numbered terms = \(\sqrt{2}\)
[\(\sqrt{2}\) = 1.4 (approximately)]
All even numbered terms = -2
Therefore sum of consecutive terms = \(\sqrt{2}\) + (-2) = \(\sqrt{2}\) - 2
Required sum = 1.4 - 2 = - 0.6 ... Answer B.....
