12+5 = 6
22+5 = 9
32+5 = 14
42+5 = 21
52+5 = 30
62+5 = 41
Square the sequence number then add 5.
The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106
The next number in the sequence is 62. The difference is doubling each time. 6-2=4 : 14-6=8 etc...

62
The next number in the sequence 3-15-6-30-21 is -207.
Clearly here the nth term isn't n25.
Each number is decreasing by 3. The next numbers in the sequence would be -18, -21, -24, -27, -30.

56 i think :) there's two sequences in this! 1st sequence: 20, 30, 42,... 2nd sequence: 5,6,7,... the first sequence goes up by the rule 2n+8 (in easier words it goes up in 10, 12, 14, 16 , 18,20, ....) and the second sequence goes up by one each time e.g. 5, 6,7,8,... hope this helped :)x

2 x 7 = 14 3 x 7 = 21 2 x 3 x 5 = 30
