If the pattern continues with rule 'multiply by 2 and subtract 1', what is the next term after 33?

If the pattern continues with rule 'multiply by 2 and subtract 1', what is the next term after 33?

• A. 63
• B. 67
• C. 69
• D. 65

Answer: (D)

This question hinges on applying a simple two-step rule to get the next term. Multiply the current term by 2, then subtract 1. Starting with 33: 33 × 2 = 66, and 66 − 1 = 65. So the next term is 65. The other options don’t fit this rule when starting from 33—63 would come from 32 (32 × 2 − 1), 67 from 34 (34 × 2 − 1), and 69 from 35 (35 × 2 − 1).
