This is called a Fibonacci Sequence where the two initial (seed) values are 1 and 3, thereafter every term is the sum of the two previous terms.
4 = 3 + 1
7 = 4 + 3
11 = 7 + 4
18 = 11 + 7
29 = 18 + 11
So the next number would be the sum of, 29 + 18 = 47
1, 3, 4, 7, 11, 18, 29, 47
It is: 47 because 18+29 = 47
18. 1+3=4 3+4=7 4+7=11 7+11=18
1 3 4 7 11 18 29 47 76 123 199 .......and so on Add together the previous two terms to find the next term i.e 1+3=4, 3+4=7, 4+7=11
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)
1+3=4 3+4=7 4+7=11 7+11=18 11+18=29 18+29=47
1, 3, 4, 7, 11, 18, 29, 47
1 3 4 7 11 18 29 and 47 add last two terms to get next term. number 4 was missing in your series
It is: 47 because 18+29 = 47
18. 1+3=4 3+4=7 4+7=11 7+11=18
1 3 4 7 11 18 29 47 76 123 199 .......and so on Add together the previous two terms to find the next term i.e 1+3=4, 3+4=7, 4+7=11
Type your answer here... 47
1, 2, 3, 6, 9, 18 1, 29
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)
(11/18) - (1/6) = (11/18) - (3/18) = (11-3)/18 = 8/18 = 4/9
47, you add the two previous numbers together: 3+4=7 4+7=11 7+11=18 18+29=47.
