1+1=2, 2+2=4, 4+4=8, 8+8=16 and so the next number in the sequence is 38

The pattern appears to involve two alternating sequences. The first sequence (3, 10, 24) increases by 7 and then by 14 (3 + 7 = 10, 10 + 14 = 24), while the second sequence (6, 20) increases by 14 (6 + 14 = 20). Thus, the next number in the first sequence would be 24 + 21 = 45, and the next in the second would be 20 + 14 = 34, which suggests the pattern continues with increasing intervals.
