✨LOTS OF POINTS✨ For each sequence write an explicit formula: 7. 1,5, 25, ... a_1:___ r/d:___ a_n:___
8. 29, 35, 41, ... a_1:___ r/d:___ a_n:___

For this sequence, write a recursive formula 9. 7,49,343, ... r/d:___ a_n:___

Step-by-step explanation:

Q7.

Given sequence

This is a GP with the first term of a₁ = 1 and common ratio r = 5

Explicit formula is:

Q8.

Given sequence

This is an AP with the first term of a₁ = 29 and common difference d = 6

Explicit formula:

Q9.

Given sequence

This is a GP with the first term a₁ = 7 and common ratio r = 7

Recursive formula is:

8

step-by-step explanation:

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
