Question

Find the missing no. 3,8,15,24,_ ?

Answer 1

The required missing number is 35.

Answer 2

Here

2*1+2-1 =3

2*3+3-1=8

3*4+4-1 = 15

4*5+5-1 =24

So next....

5*6+6-1 = 30+5 = 35

So the missing number is 35

we can also obtain it in n²-1

3=2²-1

8=3²-1

15=4²-1

24=5²-1

next is 6²-1=36-1=35

hope helped ^!
