TS EAMCET · Maths · Binomial Theorem
If the coefficients of 3 consecutive terms in the expansion of \((1+x)^{23}\) are in arithmetic progression, then those terms are
- A \(T_{10}, T_{11}, T_{12}\)
- B \(T_8, T_9, T_{10}\)
- C \(T_{13}, T_{14}, T_{15}\)
- D \(T_{14}, T_{15}, T_{16}\)
Answer & Solution
Correct Answer
(D) \(T_{14}, T_{15}, T_{16}\)
Step-by-step Solution
Detailed explanation
\(T_{\mathrm{r}+1}={ }^{23} C_{\mathrm{r}} x^x \Rightarrow\) Coefficient \(={ }^{23} C_{\mathrm{r}}\)…
