Is the sequence arithmetic, geometric, or neither

The first one is arithmetic, the second one is geometric, the third one is neither, the fourth one is geometric, the last one is arithmetic.

The first question goes up by a rate of -100 each time, so its arithmetic.

The second one goes up by a rate of *5 each time, so its geometric.

The third one is inconsistent so it is neither.

The fourth one goes by a factor of *-6 each time, so its geometric.

The last one goes up by a rate of -10 each time, so its arithmetic.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
