In each number except 427, the middle digit is sum of the other two.

The number are 1³, 2³, 3³, 4³ etc. So, 124 is wrong. It must have been 5³ i.e., 125.

The pattern is x² + 3, where x = 4, 5, 6, 7, 8, 9 etc. But 102 is out of pattern.

Double the number and add 1 to it, to get the next number. So, 160 is wrong.

Alternately, we add 3 and subtract 1.

Second number is one more than twice the first third number is one less than twice the second, fourth number is one more than twice the third, fifth number is one less than the fourth. Therefore, the sixth number is one more than twice the fifth. So, the missing number is 75.

Alternately, we add 5 and subtract 7.

Each previous number is multiplied by 2.

There are two series (10, 13, 16, 19) and (5, 10, 20, 40)one increasing by 3 and another multiplied by 2.

Each number is 15 multiplied by a prime number i.e., 15 x 11, 15 x 13, 15 x 17, 15 x 19, 15 x 23. So, the next number is 15 x 29 = 435.
