Question

31. Find the wrong number in the Series.
84,83,79,70,52,29​

Answer 1

Step-by-step explanation:

In this series 79 is the wrong number.

Answer 2

$Given \: sequence : 84,83,79,52,29$

/* Observe the pattern of the sequence */

$First \: number = \blue {84}$

$Second\: number\\ = \blue {84 } - \pink{1^{2}}\\ = 84 - 1\\=\green { 83}$

$Third\: number\\ = \blue {83 } - \pink{2^{2}}\\ = 83 - 4\\=\green { 79}$

$Fourth\: number\\ = \blue {79 } - \pink{3^{2}}\\ = 79 - 9\\=\green { 70}$

$\red{Fifth\: number}\\ = \blue {70 } - \pink{4^{2}}\\ = 70 - 16\\=\red { 54}$

$Six\: number\\ = \blue {54 } - \pink{5^{2}}\\ = 54 - 25\\=\green { 29}$

Therefore.,

$\red{Wrong \: number \: in \:the \: sequence } \green { = 52}$
