Question

A series is 11, 20, 42, 82, 166, 330 If another series 4, a, b, c, d, 106 follows the same pattern as the given number series, then find the approximate value of (c +
d) x (c –
a)%.

Q: Answer-A series is 11, 20, 42, 82, 166, 330 If another series 4, a, b, c, d, 106 follows the same pattern a...

11, 20, 42, 82, 166, 330 11 x 2 2 20 20 x 2 2 42 42 x 2 2 82 82 x 2 2 166 166 x 2 2 330 So, we will follow same pattern in series 4, a, b, c, d, 106. 4 x 2 2 6 a 6 x 2 2 14 b 14 x 2 2 26 c 26 x 2 2 54 d 54 x 2 2 106 Now, c d x c a 26 54 x 26 6 80 x 20100 16
