Solution: prime numbers are 2,3,5,7,11,13,17,19
2,(3*2),5,(7*2),11,(13*2),17,(19*2)
ans:38

10)12,22,35,68,15,28,31

ans: First we take 12 the subtract that with 1 we get next number

12-1=11 11*2=22,
35-1=34 34*2=68,
15-1=14 14*2=28,

5-10= -5 & 10*-5=- 50
Answer is -50
3.) 5,10,9,3,6,5,4,8,7,7
Solution: if we divide the series in 3 digit group then:
1st group = (5,10,9)=5*2=10-1=9
2nd group = (3,6,5)=3*2=6-1=5
3rd group = (4,8,7)=4*2=8-1=7
So the next term is 7*2=14
Answer is 14
4.) 7,4,6,3,4.5
Solution: if we divide the series in 2 digit group then:
1st group : (7,4)= 7-4=3
2nd group :(6,3)= 6-3=3
So the next term is 4.5-3=1.5
answer is 1.5
5.) 2,6,5,14,11,26,17
Solution: Prime numbers are 2,3,5,7,11,13,17,19
2,(3*2),5,(7*2),11,(13*2),17,(19*2)
answer is 38
6.)3,4,12,76,588
Solution: The difference between consecutive terms are
4-3=1 which can be written as 2^0=1
12-4=8 which can be written as 2^3=8
76-12=64 which is 2^6=64
588-76=512 which is 2^9=512
So the next term would be 2^12+588=4096+588=4684
answer is 4684
7.) -3,6,1,-2,4,-1,-1,2,-3
Solution: -3*-2=6 = 6-5=1,
