But is there a smaller multiple of 11 in the list? 198 is 11×18=198. - NBX Soluciones

Understanding the Context

A multiple of 11 is any integer that can be expressed as:

> 11 × n, where n is a positive integer (1, 2, 3, ...)

The first few multiples of 11 are:

• 11 × 1 = 11
  
• 11 × 2 = 22
  
• 11 × 3 = 33
  
• 11 × 4 = 44
  
• 11 × 5 = 55
  
• 11 × 6 = 66
  
• 11 × 7 = 77 ←
  
• 11 × 8 = 88
  
• 11 × 9 = 99 ←
  
• 11 × 10 = 110
  
• 11 × 11 = 121
  
• 11 × 12 = 132 ←
  
• 11 × 13 = 143
  
• ...

Key Insights

Back to the Example: 198 = 11×18

From the list above, 198 appears as the 18th multiple: 11×18 = 198. But is there a smaller multiple of 11 that overlaps meaningfully with this number?

The critical insight is that multiples of 11 are spaced evenly by 11 apart:

• From 11 to 198, the jump is 11 each time.
  
• The multiples just before 198 — specifically 187 = 11×17 — are close numerically.

However, 187 < 198 but is not directly linked to 198 as a smaller multiple; rather, it’s simply the prior multiple.

Final Thoughts

Is There a Smaller Multiple Present in a Given Context?

If we interpret “in the list” as referring to a specific sequence or condition (like numbers ≤ 198 or within a defined range), then yes — numerous smaller positive multiples of 11 appear earlier. For example:

• 11, 22, 33, 55, 77, 99, 110, 121, 132, 143, 154, 165, 176, 187 — all smaller than 198.
  
• All of these are valid, smaller multiples of 11 that clearly appear in any unclosed ascending list.

Summary

While 198 = 11×18 is one such multiple, it is not the smallest possible. There are many smaller multiples of 11 (like 11, 22, 55, 77, etc.) that appear earlier in any ascending sequence. Thus, in most natural or mathematical contexts involving multiples of 11 up to or including 198, smaller multiples do exist and clearly occupy positions prior to 198.

So, to directly answer: Yes — there are smaller multiples of 11 present in the set of all positive multiples of 11 consistent with 198, and many of them precede 198.
