Answer 2

The missing number(?) is "4901".

Step-by-step explanation:

The given sequence are:

11, 19, 65, 259, 1161,?

11 = $3^{2}$ + 2 =2

19 = $4^{2}$ + 3 =19

65 = $8^{2}$ + 1 = 65

259 = $16^{2}$ + 3 = 259

1161= $34^{2}$ + 5 = 1161

Similarly,

Missing number(?) = $70^{2}$ + 1 = 4901

Hence, the missing number(?) is "4901".
