203

Series Reasoning: Finding the Missing Term

The given number series is: 192, 185, 198, 191, 204, 197, 210, ?

Let's analyze the pattern between consecutive terms:

  • 192 to 185: Subtract 7 (\(-7\))
  • 185 to 198: Add 13 (\(+13\))
  • 198 to 191: Subtract 7 (\(-7\))
  • 191 to 204: Add 13 (\(+13\))
  • 204 to 197: Subtract 7 (\(-7\))
  • 197 to 210: Add 13 (\(+13\))

The pattern observed is an alternating sequence of subtracting 7 and adding 13.

Calculating the Next Number

Following the established pattern, the operation after adding 13 (\(197 + 13 = 210\)) should be subtracting 7.

Therefore, the missing number is calculated as:

\(210 - 7 = 203\)

The number that should come in place of the question mark (?) is 203.
