Writing the right-hand side as n(a_1+a_n), the equation becomes 2S=n(a_1+a_n), so the sum of the first n terms of the arithmetic series, S, is equal to one-half the number of terms multiplied by the sum of the first and last terms. That is, S= n2(a_1+a_n). Find ...
5. (a)Prove that the sum of the first n terms of an arithmetic series is given by the formula Sn=a S_n=n/2[2a+(n-1)d]where a is the first term of the series an d d is the common difference between the terms.(4)(b) Fin d the sum of the integers which are divisible by...
