Answer 2

Given

$6:5 :: 8:?$

we have to calculate the unknown value,

so we are going to evaluate the number,

let the unknown number be x

$6:5::8:x$

further solving the above equation for the value of x

First, we are going to calculate the difference between the first two number

$6-1=5$

so the difference is 1,

further for calculating the difference of value x

$8-1=7$

but the value does not match with the given option,

so $8-2=6$

Therefore the difference between the next two values is 2,

so the value of $x=6\\\\6:5::8::6$

further, the difference will be of $3$ and so on.

The final number is $6$.
