- 69 is the answer. in this we are we are doubling the difference and add it to the number to get the next number. here in this case we are adding 8,16,32,64 and so on to get next number
- 8 years agoHelpfull: Yes(24) No(0)
- 69
13*2-5=21
21*2-5=37
37*2-5=69 - 8 years agoHelpfull: Yes(9) No(0)
- double each number and subtract 5 from that
- 8 years agoHelpfull: Yes(7) No(1)
- 13+2^3=21
21+2^4=37
37+2^5=69
69+2^6=133
133+2^7=261 - 8 years agoHelpfull: Yes(4) No(0)
- 69
13+8= 21
21+16= 37
37+32= 69
69+64= 133
133+128= 261 - 8 years agoHelpfull: Yes(3) No(1)
- 69 is the ans multiple of 8 we r adding
- 8 years agoHelpfull: Yes(2) No(0)
- 69 is the answer.
- 8 years agoHelpfull: Yes(2) No(0)
- first difference is 8.
multiply it with 2 and go on.....
- 8 years agoHelpfull: Yes(1) No(2)
- 69
we are adding 8,16,32,64 and so on to get next number 37+32=69 - 8 years agoHelpfull: Yes(1) No(1)
- The difference between the no is in multiple of 8.
therefore, 64 - 8 years agoHelpfull: Yes(1) No(0)
- 69 is the correct ans-----13 21 37 (ans 69 ) 133 261
(13*2-5)=21 (21*2-5)=37 (37*2-5)=69 and so on - 8 years agoHelpfull: Yes(1) No(1)
- Difference is doubled for every term
- 8 years agoHelpfull: Yes(0) No(0)
- term's contain increment of +16
- 8 years agoHelpfull: Yes(0) No(0)
- 69 is right ans
- 8 years agoHelpfull: Yes(0) No(1)
- ans=69
21-13=8
37-21=16
by this, we can see that the increasing differnce is becoming double.so,the next diff is 32
37+32=69
133-69=64
261-133=128 - 8 years agoHelpfull: Yes(0) No(0)
- 13*2-5=21
21*2-5=37
37*2-5=69 - 6 years agoHelpfull: Yes(0) No(0)
- 69.diffirence between two numbers is increasing in doubles form
- 6 years agoHelpfull: Yes(0) No(0)
- Ans:69
because 13*2=26-5=21
21*2=42-5=37
37*2=74-5=69
69*2=138-5=133
133*2=266-5=261 - 6 years agoHelpfull: Yes(0) No(0)
- 13*2=26 then 26-5=21,
21*2=42 then 42-5= 37,
37*2=74 then 74-5=69,
69*2=138 then 138-5=133,

then answer should be 13, 21, 37, 69, 133, 261. - 6 years agoHelpfull: Yes(0) No(0)
- 13 + 2^3 = 21
21 + 2^4 = 37
37 + 2^5 = 69
69 + 2^6 = 133
so on, so ans is 69 - 5 years agoHelpfull: Yes(0) No(0)
- 69
13+8=21
21+16=37
37+32=69
69+64=133
133+128=261
In this we double the one value of 8 and 8 double 16 and 16 double 32 - 4 years agoHelpfull: Yes(0) No(0)
