Complete the analogy: A(17)D : E(89)H :: I(225)L : M(425)?

Answer & Solution
Correct answer: B.
1. Pattern: A=1,D=4 → 1²+4² = 1+16 = 17 ✓. E=5,H=8 → 25+64 = 89 ✓. 2. I=9,L=12 → 81+144 = 225 ✓. 3. M=13, missing letter x: 13² + x² = 425, so x² = 425 − 169 = 256, x = 16. The 16th letter is P. _Source: TSICET 2024 PYQ Q.26 (Shift 1, Series)_
