Question

Between two numbers whose sum is 13/6 an even number of arithmetic means is inserted ;the sum of these means exceeds their number by unity :how many means are there ?​

Answer 1

Let,

a and b be two numbers and 2n A.M.s are inserted between a and b then,

$⟹ \frac{2n}{2} (a + b) = 2n + 1 \\ \\ ⟹n( \frac{13}{6} ) = 2n + 1 \\ \\ ⟹given \: a + b = \frac{13}{6}$

➡ n = 6

∴ Number of means = 12.
