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
