Answer:
63
Explanation:
-1,5,15,29,41,63
between the 2nd term and first term, we add 6
between the 3rd and 2nd, we add 10
between 4th and 3rd, we add 14
between 5th and 4th, we add 12
to get the next term, we add 22 to the fifth tern which is 63
this is how to get the 4th term 6 interval was added to 8 making 14 and to get the fifth, then add 2 to the difference of 10 making 12. 29+12=41..so to get the last term 14 was added to 8 making 22 and therefore 41+22=63
