[(3)" rowe "(2n+7)<(n+3)^(2)],[(1100)/(3)*9*7^(n)+2*n*-1]

Find the inverse of [(1, 3),(2, 7)] by using elementary row operation.

Assertion (A) : There will be 10 rows in the flower bed if there are 23 plants in the first row , 21 in the second row , 19 in the third and so on .Also 5 rose plants are in the last row. Reason (R ) : Sum of first n terms of an A.P is given by S_(n)=(N)/(2)[2a+(n-1)d] .
