2,4,8,16,30 finish the sequence

1 answer:

4 0

260.

Subtract the nth number from the (n+1)st. You get 2, 4, 8, 14, ?
Do it again for that sequence. You get 2, 4, 6, ?
Maybe that sequence is 2, 4, 6, 8, 10, 12, 14, 16, 18, ...
If so, then the sequence "above" it is 2, 4, 8, 14, 22, 32, 44, 58, 74, ...
And the original sequence is 2, 4, 8, 16, 30, 52, 84, 128, 186, 260, ...

Answer:

10 square in.

Step-by-step explanation:

The rectangles are similar by a scale factor of 3. We can tell because the quotient of two of the corresponding sides, 18 and 6, is 3 (18/6=3)

That means the width of ABCD is 3 times the width of WXYZ.

Let's say the width of ABCD is x. Then 18*x=90 because that's the area.

x=90/18=5

Now we have the width of ABCD, 5, so to get the width of WXYZ, we divide by 3, which is 5/3.

Now to get the area of WXYZ, we can do 5/3, the width, times 6, the length, which is 30/3=10.
