Select the number that is different from the rest in the sequence 5, 11, 23, 47, 94
94
Test the rule: each term = previous term × 2 + 1.
5 × 2 + 1 = 11; 11 × 2 + 1 = 23; 23 × 2 + 1 = 47.
47 × 2 + 1 = 95, but the sequence shows 94.
Also, 5, 11, 23 and 47 are all odd numbers, while 94 is even, so it breaks the pattern.
Check: the correct sequence is 5, 11, 23, 47, 95, so 94 is the term that is different.
Hence, 94.
