If these are the only numbers give, then:
2, 10, 26 = 2 (+8), 10 (+16), 26 (+32), 58 (+64), 122...
the amount being increased keeps doubling....the sequence would read:
2, 10, 26, 58, 122...
The missing number is 26. The number after 29 is 58.
30
If the third number were 27, there is a simple solution. But with 26 there is none that I can see.
651 is the next number.
There does not appear to be a missing number. The sequence is n2 + 1. 12 + 1 = 2 : 22 + 1 = 5 : 52 + 1 = 26 : 262 + 1 = 677. The next number in the sequence is 6772 + 1 = 458330.
The missing number is 26. The number after 29 is 58.
26
The answer depends on where the missing number is meant to be. If 2, 4, 6, 10, 26, X: then X = 72 If 2, 4, 6, 10, X, 26: then X = 16.8 If 2, 4, 6, X, 10, 26: then X = 6.6 If 2, 4, X, 6, 10, 26: then X = 5.4 If 2, X, 4, 6, 10, 26: then X = 1.2 If X, 2, 4, 6, 10, 26: then X = 6
The Answer is 26
30, 20, 36, 23, 42, 26
26 Edit: a₁ = 8 , a₂= 8 + 2 = 10 , a₃& a₄up by 4, a₅ & a₆ up by 8 , .... by 16 a₄= 18 a₅ = 18 + 8 = 26 => answer
30
17. The numbers are being increased by odd numbers beginning with 3.
If the third number were 27, there is a simple solution. But with 26 there is none that I can see.
651 is the next number.
It appears that 26 and 40 are missing
