Answer 1

C is the correct answer. Hope that helped.

Answer 2

Option A .180, 161, 142, 123, 104.........

Explanation:

A pattern that begins with 180 and each consecutive number is 19 less than the previous term.

So the given sequence will be arithmetic sequence with a common difference = (-19)

Since first term of this sequence is 180 then the sequence will be

180, [ (180 - 19) = 161 ], [ (161 - 19) = 142 ], [ (142 - 19) = 123 ], [ (123 - 19) = 104 ]

180, 161, 142, 123, 104.........

Therefore, Option A is the correct answer.
