Answer 1

4-a=a-6/5
2a=4-6/5
a=2-3/5
a=7/5

Answer 2

Answer:

The value of a is $\frac{13}{5}$.

Step-by-step explanation:

It is given that $\frac{6}{5},a,4$ are in AP.

If a, b, c are in AP, the

$2b=a+c$

$2a=\frac{6}{5}+4$

$2a=\frac{6+20}{5}$

$2a=\frac{26}{5}$

Divide both sides by 2.

$a=\frac{13}{5}$

Therefore the value of a is $\frac{13}{5}$.
