Answer:
2
Step-by-step explanation:
1 is a prime number, so we cannot use it. 3 is the only odd number less than four. 2 is the only even number LESS than four. $ would be included if it was to ask for anything less than four including four. Aside from that, the only number within the range provided that meets all requirements is 2.
I also suggest using an app called photomath. It takes you through the steps of solving the equations and gives you the answer as well.
