Correct answer:

a₅ =  68.75

Step-by-step explanation:

$$\begin{gathered} a_0=78 \\ {a}_1=a_0-2=78-2=76 \\ {a}_2=a_1+4=76+4=80 \\ {a}_3=a_2-8=80-8=72 \\ {a}_4=a_3+(2+{\displaystyle \frac{1}{2}})=72+(2+{\displaystyle \frac{1}{2}})={\displaystyle \frac{149}{2}}=74\frac{1}{2}=74.5 \\ {a}_5=a_3-(3+{\displaystyle \frac{1}{4}})=72-(3+{\displaystyle \frac{1}{4}})={\displaystyle \frac{275}{4}}=68\frac{3}{4}=68.75 \end{gathered}$$
