Two numbers are 11 and 13

Step-by-step explanation:

Let us consider two numbers are a and b.

According to your question

 {a}^{2}  +  {b}^{2}  = 290

Now two numbers are consecutive positive odd numbers. So they are differ by 2 ( like 1 ,3). Then if a is greater number then a-b= 2 or a= 2+b. Put the value of a in the above equation,

( {2 + b)}^{2}  +  {b}^{2}  = 290 \\  {b}^{2}  + 2b + 2 = 145 \\  {b}^{2}  + 2b  - 143 = 0 \\ b = 11

Then a= 11+2=13.

So, the numbers are 11 and 13.
