A = \(\frac{1}{2\times3}\) + \(\frac{1}{3\times4}\) + \(\frac{1}{4\times5}\) + \(\frac{1}{5\times6}\)

A = \(\frac12-\frac13\) + \(\frac13\) - \(\frac14+\frac15-\frac16\)

A = \(\frac12-\frac16\)

A = \(\frac36-\frac16\)

A = \(\frac13\)

\(\frac{1}{2\times3}+\frac{1}{3\times4}+\frac{1}{4\times5}+\frac{1}{5\times6}\)

=\(\frac12-\frac13+\frac13-\frac14+\frac14-\frac15+\frac15-\frac16\)

=\(\frac12-\frac16=\frac26=\frac13\)
