Question

A series is 4, 5, 17, 88, 620, 5585 If another series a, b, 23, d, e, f follows the same pattern as the given number series, then find the approximate value of {a(f –
e)}/b.

Q: Answer-A series is 4, 5, 17, 88, 620, 5585 If another series a, b, 23, d, e, f follows the same pattern as...

4, 5, 17, 88, 620, 5585 4 x 1 1 5 5 x 3 2 17 17 x 5 3 88 88 x 7 4 620 620 x 9 5 5585 Now from the second series it can be conclude that, b x 3 2 23 So, b 7 When b 7, a 6. So, the whole series will be 6 x 1 1 7 7 x 3 2 23 23 x 5 3 118 d 118 x 7 4 830 e 830 x 9 5 7475 f So, af eb 67475 8307 5696
