25 = 5 * 5 : 5,

36 = 6 * 6 : 6,

49 = 7 * 7 : 7,

81 = 9 * 9 : 9,

121 = 11 * 11 : 11,

169 = 13 * 13 : 13,

225 =15 * 15 : 15.

5, 7, 9, 11, 13, 15 are an odd number but 6 is an even number. So 36 is the answer.

36 = 6 * 6 : 6,

49 = 7 * 7 : 7,

81 = 9 * 9 : 9,

121 = 11 * 11 : 11,

169 = 13 * 13 : 13,

225 =15 * 15 : 15.

5, 7, 9, 11, 13, 15 are an odd number but 6 is an even number. So 36 is the answer.

25=5*5 :5

36=6*6 :6

49=7*7 :7

81=9*9 :9

121=11*11 :11

169=13*13 :13

225=15*15 :15

There is use 5,7,9,11,13,15.. square series but 6*6+36 is not correct in this series so 36 is wrong answer.

36=6*6 :6

49=7*7 :7

81=9*9 :9

121=11*11 :11

169=13*13 :13

225=15*15 :15

There is use 5,7,9,11,13,15.. square series but 6*6+36 is not correct in this series so 36 is wrong answer.
