Answer 2

Firstly

We know

a + 3 + c + 9 = 2(b + 6)

Which on solving will give

a + c = 2b

And a=1

Thus c = 2b-1

Know according to que a=1

And difference between b.and c

should be min.

On putting b =2

We get c=3

Thus a=1 b=2 c=3..........so on

At last z = 26

Now on putting these values in que we will get

4,8,12................104 and no. Of terms 26

Now using A.P. sum formula we will

get answer as 1404
