The difference between 63 and 47 is ''16" not 17. Had it been "64" instead of 63 the explanation as well as question be correct.

I answered 32 because I thought it was the only even number in the entire series. What's wrong in that?

Add 5 to 1st number.
Then add (5+3) to the next number.
Then add (5+3+3) to the next number.
Then add (5+3+3+3) to the next number and so on.
So 47 is wrong it must be replaced by 46.

8+5=13 (5)
13+8=21 (5+3)
21+11=32 (5+6)
32+14=46 (5+9)
46+17=63 (5+12)
63+20=83 (5+15)
13+8=21 (5+3)
21+11=32 (5+6)
32+14=46 (5+9)
46+17=63 (5+12)
