Assertion(A): In the binomial expansion of (a-b)n , n ≤ 5, the sum of the 5th and 6th terms is zero, then
Reason(R): In the expansion of (x+y)n, (r+1) th term from the beginning is called the general term Tr+1 Tr+1 = nC, xn-r yr
In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A):The function
is increasing function.
Reason(R): A function f(x) is said to be an increasing function (or monotonically increasing) at an interval a < x < b, if for any two points x1 and x2 of the interval f(x1) < f(x2) when x1 < x2.
