Web20 mrt. 2024 · They are as below. To solve the summation of a sequence, you need to add the first and last term of the sequence. Later, multiply them with the number of pairs. Mathematically, S = n/2 * (a₁ + a) If you substitute the value of arithmetic sequence of the nth term, we obtain S = n/2 * [2a₁ + (n-1)d] after simplification. WebWhere a is the first item, n is the number of terms, and r is the common ratio. Also, if the common ratio is 1, then the sum of the Geometric progression is given by: S_n = na if r=1. Example: Find the sum of first n-terms of geometric sequence, where first term (a_1) = 2, common ration (r) = 2, and sum of first n-terms = 4. Solution:
WebTo find the nth term of a geometric sequence, we use T n = a × r ( n - 1 ) Sum of terms of a geometric sequence is S n = a ( rn - 1 ) ( r - 1 ) where ‘a’ is the first term and ‘r’ is the common ratio.
