Use the numbers [18, 48, 37, 25], devise an equation to reach the target number 145. You can utilize basic arithmetic operations (+, -, *, /) and each number should only be used once. Display your work in <think> </think> tags and return your final solution in <answer> </answer> tags, for example, <answer> 18 + 48 - 37 = 29 </answer> or <answer> 18 * (48 / 37) + 25 = 145 </answer>.<|im_end|>
