प्रश्नचिन्हाच्या (?) जागी कोणती संख्या असेल? [Diagram showing a stack of triangles with numbers: 3, 5, 8, 13, 22, ?] Which number will replace the question mark (?) :
The differences between the numbers are 2, 3, 5, 9, and those differences themselves grow by 1, 2, 4. The next difference is 9 + 8 = 17, so the missing number is 22 + 17 = 39.
खालील श्रेणीमध्ये कोणत्या संख्या प्रश्न चिन्हांच्या जागी येतील ? 69, 53, 76, 46, 83, ?, ?, 32, 97. In the following series, which numbers will replace the question marks ? 69, 53, 76, 46, 83, ?, ?, 32, 97.
This is an alternate series or double series. Sequence 1: 69, 76, 83, ?, 97 (+7 pattern). So 83 + 7 = 90. Sequence 2: 53, 46, ?, 32 (-7 pattern). So 46 - 7 = 39. Thus missing numbers are 39, 90.
रिकाम्या जागी कोणती संख्या येईल ? 4, 7, 11, 16, 22, 29, ______ What number will be in the blank space ? 4, 7, 11, 16, 22, 29, ______
The series increases by a progressive difference of +3, +4, +5, +6, +7, and so on. Following 29, the next difference is +8, giving 29 + 8 = 37.
