16) Write the general form of an A.P. |
|
Answer» The progression -3, 0, 3, 6, 9 is anArithmetic Progression(AP) with 3 as the common difference. Thegeneral formof anArithmetic Progressionis a, a + d, a + 2d, a + 3d and so on. Thus nth term of anAPseries is Tn= a + (n - 1) d, where Tn= nthterm and a = first term. the general form of an AP isT(n)=a+(n-1)dwherea=first termd=common differencen=number of terms Thegeneral formof an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of anAPseries is Tn= a + (n - 1) d, where Tn= nthterm and a = first term. ... The sum of n terms is also equal to theformulawhere l is the last term. |
