Each term approximately doubles the previous one and adjusts slightly:
4 → 7 (×2 − 1), 7 → 13 (×2 − 1), 13 → 25 (×2 − 1).
Following the same pattern: next = 25 × 2 − 1 = 49.
Therefore, the next term is 49.

A vertical mirror flips the letter horizontally.
The letter "E" when mirrored along a vertical axis becomes "Ǝ".
Thus, the correct mirror image is Ǝ.

The pattern shows each number as the fourth power of consecutive integers:
81 = 3⁴, 256 = 4⁴.
The next integer after 4 is 5, so the next number is 5⁴ = 625.
Therefore, 625 corresponds to 5⁴.

The sequence is 2, 5, 10, 17.
Differences between terms are 3, 5, and 7 — increasing by 2 each time.
The next difference should therefore be 9.
Add 9 to the last term: 17 + 9 = 26.
Hence, the next term in the sequence is 26.

When two congruent right triangles are joined along their hypotenuses, they form a rectangle.
This occurs because each right triangle provides half of the rectangle, and the matching hypotenuse acts as the rectangle’s diagonal.
Other combinations like isosceles triangles, circles, or squares do not form a rectangle when combined this way.
