Question

Find the Wrong Number in the series given below:
28, 66, 122, 244, 498, 1006

Answer 1

$Given \:series : \: 28,66,122,244,498,1006$

/* Observe the series , we can find following pattern */

$i )First \:term = 28$

$ii )Second \:term$

$=2 \times \blue {28} + \pink {10}$

$= 56 + 10$

$\blue { = 66}$

$iii )Third \:term$

$=2 \times \blue {66} - \red {10}$

$= 132 - 10$

$\blue { = 122}$

$iv ) Fourth \:term$

$=2 \times \blue {122} + \pink {10}$

$= 244 + 10$

$\blue { = 254}$

$v ) Fifth \:term$

$=2 \times \blue {254} - \red {10}$

$= 508 - 10$

$\blue { = 498}$

$vi) Sixth\:term$

$=2 \times \blue {498} + \pink {10}$

$= 996 + 10$

$\blue { = 1006}$

Therefore.,

$Here, \red { Wrong \: number \: is \: 244}$
