Write any two properties of determinants.

-
  1.  If all the elements of a row or column is zero then the value of the determinant is zero.
  2. If we exchange all the row and column of the determinant then value of the determinant will not change, it will remain same.
  3. If any two row or column of a determinant are identical then value of the determinant is zero.
  4. If we exchange only any two row or column of the determinant then the value of the new determinant is (-1) times of the actual value of the determinant.

Q. The sum of three consecutive terms in A.P. is 24 product is 440, find the terms. Solution: Let us assume that the numbers are a-d, a, a+d Given, (a-d)+a+(a+d)=24 ⇒3a=24 ⇒a=24/3 ⇒a=8 and (a-d)*a*(a+d)=440 ⇒(8-d)*8*(8+d)=440 ⇒(8-d)(8+d)=440/8 ⇒8²-d²=55   (since (a+b)(a-b)=a²-b²) ⇒64-d²=55 ⇒-d²=55-64 ⇒-d²=-9 ⇒d²=9 ⇒d²=3² ⇒d=±3 If d=3, then the numbers are 8-3,8,8+3 => 5,8,11 If d=-3, then the numbers are 8-(-3), 8, 8+(-3)=>8+3, 8, 8-3 =>11, 8, 5

Q. The third and sixth terms of a series in A.P  are 13 and 31 respectively. Find 20th term. Solution: Let us assume that first term=a and common difference=d. Given, third term=t₃=13 ⇒a+(3-1)*d=13 ⇒a+2d=13...................(i) and sixth term=t₆=31 ⇒a+(6-1)*d=31 ⇒a+5d=31...............(ii) (ii)-(i)⇒(a+5d)-(a+2d)=31-13 ⇒a+5d-a-2d=18 ⇒a-a+5d-2d=18 ⇒0+3d=18 ⇒3d=18 ⇒d=18÷3 ⇒d=6 Substituting the value of d=6 to the equation (i),we get (i)⇒a+2*6=13 ⇒a+12=13 ⇒a=13-12 ⇒a=1 20th term=t₂₀=a+(20-1)*d =1+19*6 =1+114 =115.
