Question

find the value of x​

Answer 1

$given \: \frac{4}{5}.x.2 \: are \: in \: ap \\ therefore \: difference \: between \: the \: successive \: terms \: are \: equal \\ therefore \: x - \frac{4}{5} = 2 - x \\ x + x = 2 + \frac{4}{5} \\ 2x = \frac{10 + 4}{5} \\ 2x = \frac{14}{5} \\ x = \frac{14}{5 \times 2} \\ x = \frac{7}{5}$

Answer 2

hey mate,...here's your answer

if there numbers are in AP, then

the condition is 2b=a+c

=

$2x = \frac{4}{5} + 2 \\ 2x = \frac{14}{5} \\ x = \frac{14}{10} \\ x = \frac{7}{5}$

hope it helps you,..

pls mark me as the brainliest,...
