If we observe the square numbers series, we can understand a pattern: 1,4,9,16,25. In other words, we have the following 1+3=4 4+5=9 9+7=16 16+9=25 In this pattern, we added 3,5,7 and 9 respectively to the previous number. In this way, to get the next numbers, we need to add 11,13,15,17 and 19 respectively to get the answer to previous number. 25+11=36 36+13=49 49+15=64 64+17=81 81+19=100 So, the five square numbers that follow 25 are 36, 49, 64, 81, 100. answer 36, 49, 64, 81, 100.
Neither of them are correct. When you plug in both of the fractions into the equation, you get answers like 2/9 (from plugging in 1/3) and 1/9 (from plugging in 1/6). None of them are equal to 9.
