Question

if the coefficients of 4 successive terms in(1+x)^n are a1,a2,a3,a4 show that A1/A1+a2 + a3/a3+a4 = 2a2/a2+a3​

Answer 1

Step-by-step explanation:

If a1 a2 a3 a4 are the coefficients

If a1,a2,a3,a4 be the coefficient of four consecutive terms in the expansio. If a1,a2,a3,a4 be the coefficient of four consecutive terms in the expansion of (1+x)^n then prove that (a1/a1+a2)+(a3/a3+a4)=2a2/a2+a3.
