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 is also the lone even number in the given series. All the other numbers are odd. Hence, 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. 5, 7, 9, 11, 13, 15 are an odd number but 6 is an even number. So 36 is the answer. |
