it has 80 that is the answer
The pattern in the sequence 139, 2781 appears to involve a multiplication and addition process. To find the next number, we can observe that 139 multiplied by 20 plus 1 equals 2781 (139 × 20 + 1 = 2781). Following this rule, we can apply the same operation to find the next number: 2781 × 20 + 1 = 55621. Therefore, the next number in the pattern is 55621.
If you mean: 5, 10, 20, 40 then the following number is twice the previous number which will be 80
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
