Answer 2

$\huge\fbox\purple{Answer}$

$\huge\tt\boxed{218}$

Difference between successive terms

• 10-3=7

• 29-10=19

• 66-29=37

• 127-66=61

Let us arrange it in a series form

7, 19, 37, 61

Now take the difference between these terms

• 19-7=12

• 37-19=18

• 61-37=24

So the difference is a multiple of 6.

So the next difference is 30.

• X-61=30

• X=91

So now looking to our original series

after 127 the next no is

➝ 127+91=218

➝ X-127=91

So next number in the series is 218
