58 59 61 65 73 ?
Series Pattern Analysis
Examine the differences between consecutive terms in the series: 58, 59, 61, 65, 73, ?
- Difference between 59 and 58: \(59 - 58 = 1\)
- Difference between 61 and 59: \(61 - 59 = 2\)
- Difference between 65 and 61: \(65 - 61 = 4\)
- Difference between 73 and 65: \(73 - 65 = 8\)
Identifying the Progression
The differences are 1, 2, 4, 8. This sequence represents powers of 2:
- \(1 = 2^0\)
- \(2 = 2^1\)
- \(4 = 2^2\)
- \(8 = 2^3\)
The pattern shows that the difference between terms increases as successive powers of 2.
Calculating the Next Term
The next difference in the pattern should be the next power of 2, which is \(2^4\).
- Next difference: \(2^4 = 16\)
To find the missing term (?), add this difference to the last term of the series (73):
- Missing term = \(73 + 16\)
- Missing term = \(89\)
Therefore, the number that should come in place of ? is 89.
