Question

Find the next number 1)15, 18, 21, 24, 2) 1, 4, 9, 16, 25,

Gaurav Dangi · Answer

1) 15 + 3 = 18
18 + 3 = 21
21 + 3 = 24
24 + 3 = 27
27 + 3 = 30 and so on add three to every number

2) 1 + 3 = 4
4 + 5 = 9
9 + 7 = 16
16 + 9 = 25
25 + 11 = 36
36+ 13 = 49
49 + 15 = 64
and so on keep adding odd numbers 17, 19, 21, 23
