लुप्त संख्या ज्ञात कीजिए:
21, 34, 55, 89, 144, ?
Options:
- 199
- 243
- 233
- 289
- 199
- 243
- 233
- 289
Correct Answer: c)
Explanation:
This is a Fibonacci sequence where each term is the sum of the two preceding terms:
\(21 + 34 = 55\)
\(34 + 55 = 89\)
\(55 + 89 = 144\)
\(89 + 144 = 233\).
यह फिबोनाची शृंखला है जिसमें प्रत्येक पद पिछले दो पदों का योग है:
\(21 + 34 = 55\)
\(34 + 55 = 89\)
\(55 + 89 = 144\)
\(89 + 144 = 233\)।
