AI explanation

The pattern in this series involves multiplying by 2 and then subtracting an increasing even number. Following this logic, 510 multiplied by 2 is 1020, and subtracting 2 gives 1018, which does not match the first term. Alternatively, working backwards, 3 multiplied by 2 is 6, plus 10 gives 16; 16 multiplied by 2 is 32, plus 14 gives 46. Continuing the pattern of adding numbers increasing by 4, 46 multiplied by 2 is 92, plus 18 gives 110 instead of 106. The wrong number is 106.
