 Solution For given arithemetic progression series 7,3,-1,-5,-9 ,... find 10 th term and addition of first 10 th terms.Solution:Your problem -> For given arithemetic progression series 7,3,-1,-5,-9 ,... find 10 th term and addition of first 10 th terms.Here first term a = 7,d = 3 - 7 = -4We know that, f(n) = a + (n - 1)df(10) = 7 + (10 - 1)(-4)= 7 + (-36)= -29We know that, S_n = n/2 [2a + (n - 1)d]:. S_10 = 10/2 * [2(7) + (10 - 1)(-4)]= 5 * [14 + (-36)]= 5 * [-22]= -110Hence, 10^(th) term of the given series is -29 and sum of first 10^(th) term is -110 Solution provided by AtoZmath.com Any wrong solution, solution improvement, feedback then Submit Here Want to know about AtoZmath.com and me
