Question 698750
Solution:
Given sequence is: 1,2,3,5,?,13,21,? 
here we can see that : third term is obtained by adding the first two term, 
in similar way fourth term 5 is adding second two terms , 
hence 5 term = 3 + 5 
= 8 
and the last term is = 13 + 21 
34 

hence the sequence would be: 
1,2,3,5,8,13,21,34
