NFST Logical and Spatial Reasoning 2

Question 1

What is the next number in the sequence: 3, 7, 15, 31, 63, ___?

Accepted Answer

127

Answer

Each term is double the previous term plus 1: 63×2+1=127.

Question 2

If all firefighters are first responders, and some first responders are paramedics, which statement must be true?

Accepted Answer

Some firefighters may be paramedics

Answer

Since only some first responders are paramedics, firefighters (a subset) could overlap with paramedics but it is not guaranteed.

Question 3

What is the next letter in the sequence: A, C, F, J, O, ___?

Accepted Answer

U

Answer

The gaps increase by one each time (+2, +3, +4, +5, +6), so O (position 15) + 6 = U (position 21).

Question 4

A fire truck parked facing North turns 90° clockwise, then 180° counterclockwise. What direction is it now facing?

Accepted Answer

West

Answer

North + 90° clockwise = East; East + 180° counterclockwise = West.

Question 5

A fire hose fills a 500-gallon tank in 10 minutes. How many tanks can it fill in 45 minutes?

Accepted Answer

4.5

Answer

45 minutes ÷ 10 minutes per tank = 4.5 tanks.
