(D) 26/5​

Answer 1

$Given \: 4,a,\frac{6}{5} \: are \: in \: A.P$

$We \: know \:that ,$

$\pink{ If \: a,b,c \: are \: in \: A.P}$

$\pink{ 2b = a + c}$

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

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

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

$\implies a = \frac{26}{10}$

Therefore.,

$\red{ Value \: of \: a}\green { = \frac{26}{10}}$

$\red{ Options \: given \: are \: wrong }$
