18^{\text {th}}

term of the sequence

72,70,68,66, \ldots

40.

II.

4^{\text {th}}

term of the sequence

8-6 i, 7-4 i, 6-2 i, \ldots

is purely real.

Choose the correct option.

View answer and explanation

Correct option: B

Only II is true

Option B (Only II is true) is correct because the 18th term of the first sequence is not 40, while the 4th term of the second sequence is purely real.
