1, 3, 4, 7, 11, 18, 29, 47
The next two numbers are 26 & 78.
47, you add the two previous numbers together: 3+4=7 4+7=11 7+11=18 18+29=47.
The pattern is add three and then multiply by three. The next number is 174.
42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
18. 1+3=4 3+4=7 4+7=11 7+11=18
If you mean 4 11 18 25 then the next number is 32 because the numbers are increasing by increments of 7
The next two numbers are 26 & 78.
They are reducing by 4.5 each time. So the next two numbers are 9 and 4.5 after that.
Adding consecutive odd numbers
47, you add the two previous numbers together: 3+4=7 4+7=11 7+11=18 18+29=47.
The pattern is add three and then multiply by three. The next number is 174.
20-23
30, 42, 38
It is -9 because the numbers are decreasing by 18 each time
42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
18. 1+3=4 3+4=7 4+7=11 7+11=18
162 and 486 the pattern is that the next number is three times the previous number.
