Question

in a GP find the sum.
GP=
$ar + a{r}^{2} + a{r}^{3}+ a{r}^{4}+... + a{r}^{2n}$
instructions
1) calculate by taking first term = ar.
2) calculate by taking common r from each.​

Answer 1

Answer:

In Maths, Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio. This progression is also known as a geometric sequence of numbers that follow a pattern. Also, learn arithmetic progression here.

The common ratio multiplied here to each term to get a next term is a non-zero number. An example of GP is 2, 4, 8, 16, 32, 64, …, where the common ratio is 2.
