Analysis of Lens Combination:
- The power of the first lens (P1) = -1 diopter
- The power of the second lens (P2) = +2.5 diopter
- The power of the third lens (P3) = -0.5 diopter

Calculation of Combined Power:
To find the combined power of the three lenses, we use the formula for combining lenses in contact:
1/F = 1/f1 + 1/f2 + 1/f3
where F is the combined power and f1, f2, f3 are the powers of the individual lenses.
Substituting the given values:
1/F = 1/-1 + 1/2.5 + 1/-0.5
1/F = -1 + 0.4 - 2
1/F = -2.6
F = 1/-2.6
F ≈ +1 diopter

Explanation of Diverging Nature:
- When the combined power of the lenses is positive, it indicates that the overall effect is diverging in nature.
- Diverging lenses have negative focal lengths and cause light rays to spread out.

Verification of Both A and R:
- A (Assertion): The combination of lenses is diverging in nature.
- R (Reason): The combined power of the lenses is +1 diopter.

Explanation of A and R:
- The assertion is correct because a positive combined power indicates a diverging nature.
- The reason is also correct as it aligns with the calculated combined power of the lenses.
Therefore, both A and R are true, and the explanation supports their validity.
