### Instruction: help me answer this question Find the 4th term in the expansion of (x – 2y)12., think step by step
### Assistant: The general term Tr+1 in the binomial expansion is given by Tr+1 = n C r an-r br. Here, a= x, n =12, r= 3 and b = -2y. By substituting the values, we get T4 = 12C3 x9 (-2y)3 = -1760 x9 y3. , The answer is T4 = 12C3 x9 (-2y)3 = -1760 x9 y3
