what is next in the series (1) 12 14 18 26 38_?

Question

(2) 23 57 1113 1719 _(3) 38 49 62 70 77 _ (4) 49 1625 3649 _
(5) 12 36 324 2916 _ (6) 1 2 6 42 _ (7 ) 1 4 6 8 9 10 _

Answer 1

these are my results


48
Method: Add 2 more than the previous difference (+2,+4,+6 etc)

(2) 2329
Method: Groups of prime numbers together. 2 and 3 = 23, 5 and 7 = 57. 23 and 29 are the next two prime numbers.

(3) 91
Method: Add all the previous digits together, i.e 3+8+4+9 etc

(4) 6481
Method: Same as answer 2 but for squared numbers.

(5) ??


(6) 2142
Method: Add the previous numbers together and multiply by the single previous number.

(7) 11
Method: I googled it. It's a Smarandache sequence with all 2,3,5,7 integers removed

Answer 2

12 14 18 26 38_
62
this is a series where
12+1*2 = 14
18 + 1*8 = 26
26 + 2*6 = 38
so 38 + 3*8 = 62

~~~~~
23 57 1113 1719 _
2329
This is prime series:
2 3 5 7 11 13 17 19 23 29
see that if you put two primes together, it will generate your sequence
'2 3' '5 7' '11 13' '17 19' '23 29'

~~~~
38 49 62 70 77
91
See that:
38 + 3 + 8 = 49
49 + 4 + 9 = 62
62 + 6 + 2 = 70
70 + 7 + 0 = 77
so 77 + 7 + 7 = 91

~~~~
49 1625 3649 _
2 36 324 2916 _
don't know about these

~~~~
1 2 6 42 _
there might be many solution to this sequence, see:

~~~~
1 4 6 8 9 10 _
12
A sequence of nonprime numbers
This means all composite number and 1. The Prime number sequence is
2 3 5 7 11 13 ....

Answer 3

Liars never lies answers to #s 1, 2, 3, and 7 are correct.
4) 49 1625 3649 _ next is 6481
2*2=4 3*3=9 49
4*4=16 5*5=25 1625
6*6=36 7*7=49 3649
so next is 8*8=64 9*9=81 or 6481

5) 12 36 324 2916 _
12*(1+2)=36
36*(3+6)=324
324*(3+2+4)=2916
so next is 2916*(2+9+1+6)=52488

6) 1 2 6 42 _
1*1+1=2
2*2+2=6
6*6+6=42
so next is 42*42+42=1806

Answer 5

(a million) 2, 5, 11, 20, 32, 40 seven, ? (sixty 5) - Going from the first huge form to the 2d, you upload a million*3. Going from the 2d to the 0.33, you upload 2*3. From the 0.33 to the fourth, upload 3*3. Then 4*3, 5*3, and six*3. (2) 38, 36, 30, 28, 22, ? (20) - Going from an effortless huge form to an excellent huge form, you oftentimes subtract 2. (3) a million, 3, 9, 27, 80 one, ? (243) - each new huge form is the previous huge form circumstances 3. (4) 9, 4, 10, 5, 11, 6, ? (12) - each new even huge form is a million more beneficial than the previous effortless huge form. a similar is going for the effortless numbers. (5) one thousand miles in line with month, each 4000 miles (3) - considering that there are 3 hundred and sixty 5 days in a year, which ability you stress 12000 miles in line with year. Divide that by ability of 4000 miles and get 3. (6) 13, 18, 16, 21, 19, ? (24) - each new even huge form is 3 more beneficial than the previous effortless huge form. a similar is going for the effortless numbers. (7) 4, 12, 6, 12, 36, 18, 36, ? (108) - From one huge form to the subsequent, in communities of three, multiply by ability of three, divide by ability of two, multiply by ability of two, then repeat. (8) 40 six, 40 5, 40 3, 40, 36, ? (31) - Subtract a million more beneficial than you probably did from the previous huge form. Subtract a million, then subtract 2, then 3, then 4, and ultimately subtract 5. (9) 20, 23, 28, 14, 17, 22, 11, ? (14) - From one huge form to the subsequent, in communities of three, upload 3, upload 5, divide by ability of two, then repeat. (10) $25 bill, 20% ($5) - Multiply 25 by ability of 0.2 to get the end. (11) 2.5 miles in line with hour, 12.5 miles finished (5.0) - price x Time = Distance, so Time = Distance ÷ price. (12) 18, 9, 11, 14, 7, 9, 12, ? (6) - From one huge form to the subsequent, in communities of three, divide by ability of two, upload 2, upload 3, then repeat.

Answer 6

12 +2 = 14
14+4 = 18
18+8=26
26 + 12=38 ?????

sure you didn't miscopy the first problem? the sequence would make sense easily if it was 36... in which case the next number would be 48
it was looking like a simple +2(N) sequence until that 38 popped up..

Answer 7

(1)40

Answer 8

I think that if you had looked at this for as long as it took you to write it on here you would have worked it out.

Answer 9

(1) 50

Answer 10

next in sequence is number 54.
