Consider the pattern shown below:
`{:(" Row ",1,1,,,),(" Row ",2,3,5,,),(" Row ",3,7,9,11,),(" Row ",4,13,15,17,19):}etc.`
The number at the end of row 60 is

The odd numbers are divides as follows : {:(,,1,3,,),(,5,7,9,11,),(13,15,17,19,21,23):} "…………………………………………………….." then the sum of nth row is :

Find the rank of the following matrices by row reduction method : [{:(1,1,1,3),(2,-1,3,4),(5,-1,7,11):}]

In each of the following questions, the two rows of numbers are given. Resultant number in each row is to be worked out seperately based on the following rules and the question below the row of numbers is to be answered. The operations of numbers progress from left to right. Rules: (i) If an even number is followed by a prime number they are to be multiplied. (ii) If an even number is followed by a composite odd number, odd number is to be subtracted from even (iii) If a composite is followed by a prime number, the first number is to be divided by the second number. (iv) If an odd number is followed by an even number which is a perfect square, they are to be added. (v) If an odd number is followed by another odd number they are to be added. Now work out the resultant numbers for each row in each question and answer the question below the rows of numbers. 39 13 11 17 24 5 55 13 What is the difference between resultants of the two rows? 1) 14 2) 9 3) 243 4) 233 None of these

In the matrix [[1,0,5],[2,-3,4]] i. number of rows is……………………...
