Answer 1

Step 1

Define the terms in the given function

`y=((a)/(a+b))(y_2-y_{1_{}})+y_1`

Where

`\begin{gathered} a=5 \\ b=2 \\ y_2=3 \\ y_1=1 \end{gathered}`

Step 2

Substitute and get the required formula

`\begin{gathered} ((5)/(2+5))(3-1)+1 \\ ((5)/(7))(3-1)+1 \end{gathered}`

Hence option 3 is right
