Question

Write which number replaces the questions mark in the sequence.

$11\frac{1}{9},12\frac{1}{2},14\frac{2}{7},16\frac{2}{3},?$

• A. $8\frac{1}{3}$
• B. $19\frac{1}{2}$
• C. $20$
• D. $22\frac{1}{3}$

Answer 1

The correct option is C $20$

$11\frac{1}{9},12\frac{1}{2},14\frac{2}{7},16\frac{2}{3}$ can be written as

$\frac{100}{9},\underset{\underset{\frac{100}{8}}{\Downarrow }}{\frac{25}{2}},\frac{100}{7},\underset{\underset{\frac{100}{6}}{\Downarrow }}{\frac{50}{3}}\Rightarrow \frac{100}{5}=20$.

So, the next term will be $20$.
