Answer 2

x = 149

Step-by-step explanation:

The given series are:

10, 11, 17, 43, x, 575

To find, the value of x = ?

+ 1, + 6 (1 × 4 + 2), 26 (6 × 4 + 2),  + 106(26 × 4 + 2), + ........

11 = 10 + 1 = 11

17 = 11 + 1 × 4 + 2 = 11 + 6 = 17

43 = 17 + 6 × 4 + 2 = 17 + 26 = 43

x = 43 + 26 × 4 + 2 = 43 + 106 = 149

575 = 149 + 106 × 4 + 2 = 149 + 424 + 2 = 575

∴ x = 149
