Directions: In the following question, a number sequence is given with one term missing. Choose the correct term that will continue the same pattern and replace the question mark in the given sequence.4,6,12,14,28,30,?
Correct answer: B. 60
- A. 32
- B. 60
- C. 62
- D. 64
Explanation
The sequence alternates between adding 2 and multiplying by 2, starting with addition: 4 + 2 = 66 x 2 = 1212 + 2 = 1414 x 2 = 2828 + 2 = 3030 x 2 = 60The correct answer is 60, which fits the established pattern. The other options do not follow this pattern, either incorrectly adding or not multiplying by 2 when required.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
