For this case we have the following sequence:

a_ {n} = \frac {3} {n (n + 1)}

We must find the value ofa_ {10}, then, substituting n = 10 in the formula we have:

a_ {10} = \frac {3} {10 (10 + 1)}\\a_ {10} = \frac {3} {10 * 11}\\a_ {10} = \frac {3} {110}

ANswer:

a_ {10} = \frac {3} {110}

Answer:

\large\boxed{a_{10}=\dfrac{3}{110}}

Step-by-step explanation:

Put <em>n = 10</em> to the equation a_n=\dfrac{3}{n(n+1)}

a_{10}=\dfrac{3}{10(10+1)}=\dfrac{3}{10(11)}=\dfrac{3}{110}
