=7

Step-by-step explanation:

Answer 2

The value of a is $11/8$.

Explanation:

• By the given equation we can consider $a_{1}=3/4$, $a_{2}=a$, $a_{3}=2$.
• According to the AP rule $a_{2} -a_{1} =a_{3}- a_{2}$.
• Substituting the values we get, $a-3/4=2-a$.
• Now we are grouping the variables and constants at one side. So, we have $a+a=2+3/4$.
• Taking the LCM on right hand side we get $2a=11/4$.
• Hence the value of a is  $11/8$.
