WebExample 1: In a GP, the sum of the first three terms is 16, and the sum of the next three terms is 128. Find the sum of the first n terms of the GP. Solution: Let 'a' and 'r' be the first term and the common ratio of the given GP respectively. Then: a + ar + ar 2 = 16 ar 3 + ar 4 + ar 5 = 128. We can rewrite these equations as: WebTo find the n th term of a GP, we require the first term and the common ratio. If the common ratio is not known, the common ratio is calculated by finding the ratio of any term to its … shapes i know slaughter beach dog
Harmonic Progression (HP) - Definition, Formulas, Examples
WebIn a GP, the nth term of a GP is given by: an=arm-1. The tutorial will show you how to compute the sum of first n terms of a GP. When r=1, the GP can be treated as an AP, and clearly the sum of first n terms then is “nXa”. Similar to an AP, m th term from the end is (n-m+1) th term from the starting. WebSolution The correct option is C ( m n) Explanation for the correct option Step 1: Information required for the solution Let a be the first term of GP with a common ratio r Then the last term of the GP will be a r n - 1 The p + q th term will be, a r ( p + q - 1) = m … 1 The p - q th term will be, a r ( p - q - 1) = n … 2 WebMar 30, 2024 · Here in this question, we are given that the nth term of the sequence is $ {T_n} = 128 $ and the sum of n terms is $ {S_n} = 255 $ . Also, the common ratio of the sequence $ r = 2 $ . And we are asked to find the first term of the sequence. We will use the formula for the sum of n terms of a G.P to get the first term. ponytails for curly hair
