If the rule is 'double then subtract 1' starting from 3 for each step, what is the second term?

If the rule is 'double then subtract 1' starting from 3 for each step, what is the second term?

• A. 5
• B. 4
• C. 7
• D. 8

Answer: (A)

This question is about applying a two-step rule to generate the next term in a sequence. Start with three. Double it to get six, then subtract one to get five. So the second term is five. If you tried a different result like four, seven, or eight, that would come from doing the steps in a different order or changing the operation, which isn’t allowed by the rule.
