Matric Part 1/9th Class General Math Chapter 7 Short Questions Test With Answer for Unit 7 Arithmetic and Geometric Sequences

Find the following term 9,11,14,17,19,22....?

• Ans 1:

Find the missing element using fotmula A.P?

• Ans 1:

What is Geometric Progression?

• Ans 1: A geometric progression (abbrivated as G.P) is a sequence of numbers called terms,each of which after the first is obtained by multiplying the precedign by a fixed number called common ratio.This comon ratio is denoted by 'r' which can not be zero in any case.We can obtained common ratio as: a_n=ar^n-1

• Ans 1:

What is Arithmetic means between two numbers?

• Ans 1: Let A₁,A₂..........A_nbe "n" A.Ms between the two numbers a and b, such that a A₁,A₂..........A_n is an A.P. Here a₁=a,A_n+2=b because there are n+2 terms in an A.P. Formula=a_n+2=a+(n=2-1)d

What si Finite and Infinite Sequence?

• Ans 1: If there is a last term in a sequence, it is called a finite sequence.If there is not a last term in a sequence ,it is called an infinite sequence.

What is Sequence (Progression)?

• Ans 1: A sequence is an arrangment of number written in definite order according to some specific rule .A sequence is also called progression.

What is Arithmetic Sequence?

• Ans 1: An arithmetics progression (abbrivated A.P) is a sequence of number called terms,each of which after the first is obatined from the preceding one by adding to it a fixed number called "common difference " of the progression.
