Question

19,24,21,26,23,_,_ What will come there ​

Answer 1

Answer:

Step-by-step explanation:

19. area of trapezium=1/2*(sum of parallel sides)*h

                                 =1/2*(6.6+8.4)*6

                                 =1/2*15*6

                                 =45

20.here AC is the diagonal of parallelogram ABCD

   so, it bisects the parallelogram ABCD into two equal parts

   ar(ABC)=ar(ACD)=30

   ar(ABC)+ar(ACD)=ar(ABCD)

   30+30=60

21.diameter=r

   radius=1/2d

   area=πr²

          =π(1/2d)²

          =πd²/4

22. let the areas of the circle be 4x and 9x

    area=πr²

    area of both circles =π(r₁)²=4x and π(r₂)₂=9x

     ATQ

    4x/9x=π(r₁)²/=π(r₂)²

    4/9=(r₁)²/(r₂)²

    so, r₁=2 and r₂=3

   now d₁=4 and d₂=6

   their ratio is 4/6=2/3=2:3

23. it is given that

    the side of a square = the radius of a circle=r

    ATQ

   r₂/πr²

  =1/π

  =1:π

Answer 2

Explanation: The rules could truly be anything, but I’m assuming a loop in relationships is actually a loop and not a brilliant scheme for a series pattern that might actually have a bunch of steps.
