Question

Four sizes of scaled text are shown.

What is the unknown scale size?

Answer 1

Are those the answers ^ ??

Answer 2

Unknown scale size is 1.25

Explanation:

There are four sizes are of scaled text shown in the picture.

Scaled text text means 3rd text is multiplied with a common factor to give the 4th text.

Finally we can say that we are getting these images scaled in a geometric sequence.

Now we have to get the second term of this sequence.

1, ?, 1.563, 1.954

Since explicit formula of a geometric sequence is
`f(x)=ar^(n-1)`

Here a = first term of the sequence

r = common ratio

n = number of term

Now common ratio = r = 4th term/third term = 1.954/1.563 = 1.25

Now 2nd term =
`ar^(2-1)=1.(1.25)^((2-1))=1.25`

Therefore unknown scale size is 1.25
