Read Solution (17) :

Courtney Hopkins  (7 years ago)

12) 2, 3, 10, 15, 26

1^2+1=2
2^2-1=3
3^2+1=10
4^2-1=15
5^2+1=25
6^2-1=35

Thus the answer is 35

15) Split the series as following :
4, 2, 36, 4
5, 1, 36, 16
6, 3, 81, ?
Now in each part we can observe that (1st term + 2nd term)^2 = 3rd term and (1st term - 2nd term)^2 = 4th term.
Thus required term is : (6 -3)^2 = 9

Is this solution Helpfull? Yes (5) | No (1)  

NITISH SATI  (7 years ago)

18) Add two terms and divide by 3rd from series and then you will get 4th terms of series
0+1/2=0.5
2+3/5=1
2+0/2=1
4+2/3=2 (it is answer)

(1)
28,17,23,17, 26,16,22,16,24,15,21,15,?
divide into two series.
28, 23, 26, 22, 24, 21, ?
(-5, +3, -4, +2, -3, ...... next +1 so next number is 21+1= 22)
&
other series 17,17,16,16,15,15,..... so next is 14,14
so now ans is 22,14

Is this solution Helpfull? Yes (2) | No   

dheeraj kumar  (7 years ago)

1) 28 17 23 17 26 16 22 16 24 15 21 15 ?
Ans: 20
In this series form a series that is...
28 23 26 22 24 21
Difference between the terms..
28-23=5
23-26=-3
26-22=4
22-24=-2
24-21=3
So 21+1=22
because difeerence is like that 5 -3 4 -2 3 so next is -1

Courtney Hopkins  (7 years ago)

14. We must break the series into two parts, as it is an interleaved series

5, 7, 9, 11, 13, 15, 17 (odd)
5, 7, 11, 13, 19, 23 (prime numbers)

thus the answer is 23 as it is the next prime number in the second part
