The following series 1)v is 30. n+4 n-0 convergent (a) divergent (b) (c) satisfies both the conditions of leibnitz test (d) none

see attached if any doubt then ask

At first, the terms of √n/(n+4) do not seem to be monotone, but as n increases, it starts decreasing, and tends to 0. Therefore it satisfies Leibniz test, and it is convergent.
