A) N B) M C) L D) O
Answer: ✅ A) N
Explanation:
Alphabet positions: Z(26), X(24), U(21), Q(17), N(14)
Diffs: -2, -3, -4, -5

6. Complete the series:

1, 4, 9, 16, 25, ?

A) 35 B) 36 C) 30 D) 49
Answer: ✅ B) 36
Explanation:
It’s squares: 1², 2², 3², …, so next is 6² = 36

7. What comes next?

121, 144, 169, 196, ?

A) 225 B) 205 C) 210 D) 230
Answer: ✅ A) 225

11² = 121, 12² = 144, 13² = 169… next is 15² = 225

8. Complete the series:

A, C, F, J, O, ?

A) S B) T C) U D) V
Answer: ✅ C) U
Explanation:
Alphabet positions: A(1), C(3), F(6), J(10), O(15), U(21)
Differences: +2, +3, +4, +5, +6

9. What comes next in the series?

5, 11, 23, 47, ?

A) 95 B) 94 C) 96 D) 93
Answer: ✅ B) 94
Explanation:
×2 +1 → 5×2+1 = 11
×2 +1 → 11×2+1 = 23
×2 +1 → 23×2+1 = 47
47×2 +1 = 95

Oops! The pattern breaks. Check again:
Diffs: 6, 12, 24 → doubling each time.
11-5 = 6
23-11 = 12
47-23 = 24
So next diff = 48 → 47 + 48 = 95

✅ Correct Answer: A) 95

10. What comes next in the series?

1, 8, 27, 64, ?

A) 100 B) 125 C) 81 D) 99
