Is about a Arithematic and Geometric Progession questions Question: 1.The first term of a geometric progression exceeds 8 from the second term and the sum to infinity of the geometric progression is 18. Find the common ratio and the first term of the geometric progression. 2.The 8 term of an arithmetic progression is 20 and the 7 term is four times the 3 term.Find the first term and the common difference of the progression.
