Answer 2

This is clearly not a typical ratio question.

Here's one way of solving the first one:

2: (2+1)² = 3² =9

Similarly, 64: (64+1)²=65²= 4225

In other words, add 1 to the first number and square it.

For the second one:

This is a bit tricky...

18 = 2 × 3²

48 = 3 × 4²

180 = 5 × 6²

So , answer must be 6 × 7² = 6 × 49 = 294

Pls mark as brainliest, no one else knows the answer to these two questions!

Hope this helps! :D
