Find The Missing Number In The Series; 9, 20, 44, ?, 196

In the series, the numbers are doubled and then added with the number 2 which is increased by 2 each time.

So the sequence is as follows;

Next number after 9 = 9 x 2 + 2 = 18 + 2 = 20;

Next number after 20 = 20 x 2 + 2 + 2 = 40 + 4 = 44;

So the missing number would be;

Next number after 44 = 44 x 2 + 4 + 2 = 88 + 6 = 94

Let’s check if that is the correct answer by seeing if it results in the last number;

Next number after 94 = 94 x 2 + 6 + 2 = 188 + 8 = 196 = equal to last number in the sequence.

Hence;

Answer = 94
