A10
B9
C8
D7 ✓ Correct
Correct answer: (D) 7 — The answer is 7.
Explanation
★The answer is 7.
★The series runs in pairs, where the second number is one less than the first.
★The pairs are 2 and 1, then 4 and 3, then 6 and 5.
★The next pair starts with 8, so its second number is 8 minus 1.
★That is 7.
★So the missing term is 7.
★So the answer is 7.
