Answer 1

Answer:

Mark my answer as brainliest... Answer is 48

Step-by-step explanation:

If we take the numbers, a1 a2 a3 _ _ _ a8

then according to question a4+a5 / 2 = 6

As the numbers are in sequence ( kramik sankhya )

so from here we can conclude that a1+a8/2 = 6

a2+a7/2 = 6

a3 + a5/2 = 6

So from above, adding all of them

we get

a1+a2+a3+a4+a5+a6+a7+a8 / 2 = 24

multiplying 2 by both side , we get a1+a2 _ _ _  a8 = 48

Sum/ Yogfal  = 48
