Answer 2

Step-by-step explanation:

2,9,28,65,126,__ (1)

Here,

9-2 =7,

28-9=19,

65-28=37,

126-65=61,

so the another chain is 7, 19, 37, 61, (2) difference between each number is 12,18,24,

In this numbers, the difference is of 6.

To get the next number of 24 Add 6 in it.

24+6=30. Then again 30 + 6=36.

Then the chain will be 12,18,24,30,36 (3)

After that,

from (2),

62+30=91

91+36=127

then the continuous chain of (2) will be

7, 19, 37, 61, 91, 127. (4).

From (1) and (4)

2, 9, 28, 65, 126

+ + + + +

7, 19, 37, 61, 91

like this

2+7= 9,

9+19=28,

28+37=65,

65+61=126,

126+91=217

so the ans is

9, 28, 65, 126, 217
