the series is 2n+3 with n being the previous number
2(5)+3=13
2(13)+3=29
2(29)+3=61
2(61)+3=125
2(125)+3=253<----answer
13 ...23 ...33 ...43 ...53=125■
125Double the difference each time61-29=32so 32x2=64then 64+61=125

13 ...23 ...33 ...43 ...53=125■
The next number will be 13+21 = 34
125Double the difference each time61-29=32so 32x2=64then 64+61=125
The sequence alternates between a number and that number plus one. After 2 comes 3, after 3 comes 12, after 12 comes 13, after 13 comes 52, and after 52 comes 53. Following this pattern, the next number after 53 would be 212, as it follows 52 multiplied by 4 (the previous non-incrementing number). Therefore, the next number in the sequence is 212.
The series is n3: 13, 23, 33 ...The next number is 216.

17 cause it is the next prime number
13/0.104 = 125 Therefore, 13 is 10.4 percent of 125.
