Explanation Given information: The given sequence is, 1 3 , − 2 3 , 4 3 , ... Concept used: Sequence: A listing of terms a n is known as Sequence, where n is a natural number. Series: A sum of the terms of a sequence is called a series. Summation Notation: A shorthand notation for denoting a series when the general term of the sequence is known is called summation notation. It is denoted by letter sigma ( ∑ ) . Write the expression for n t h term of ageometric sequence, a n = a 1 r n − 1 Here, the first term is a 1 , the product of each term of the series and the preceding term is r , and the number of terms is n . Write the partial sum formula for a geometric sequence, S n = a 1 ( 1 − r n ) 1 − r The given sequence is, 1 3 , − 2 3 , 4 3 ,
