Two series are given as under
(a) \(\rm 1-\frac{1}{2}+\frac{1}{4}-\frac{1}{8}+\frac{1}{16}-\frac{1}{32}+.....upto \ \infty\)
(b) \(\rm 2+\sqrt2+1+\frac{1}{\sqrt2}+\frac{1}{2}+\frac{1}{2\sqrt2}+...... upto \ \infty\)
Choose the correct option:
1
(a) is convergent while (b) is divergent series
2
Both (a) and (b) are convergent series
3
(a) is divergent while (b) is convergent series
4
None of (a) and (b) are convergent
