Question

1,5,15,29,? what is the next number

Answer 1

i think your question is -------------> -1 , 5, 15 , 29 ,? what is the next number?

here if we subtract two regular terms we get,

5 - ( -1 ) = 6 = 6 + 4 × 0

15 - 5 = 10 = 6 + 4 × 1

29 - 15 = 14 = 6 + 4 × 2

similarly, x - 29 = 6 + 4 × 3 = 18

x = 29 + 18 = 47

hence, next term is 47
