This is an a word problem but I cannot find the pattern of the problem. I'm also having trouble finding the pattern and who much it's increasing.

Thats pretty much it.

sequence s is defined as Sn = sn-1 +20

what's the explicit formula to the sequence 1/2 , 1 , 3 , 12 , 60 , 360 , 2520 , ...? Multiplies by one larger number each time but how to put that into an explicit formula?

9. The first two terms of an infinite geometric sequence, in order, are 2log2x, log2x, where x > 0. a. Find r. b. Show that the sum of the infinite sequence is 4log2x. c. The first...

6. Consider a geometric sequence where the first term is 768 and the second term is 576. Find the least value of n such that the nth term of the sequence is less than 7.

If the eighth term of a geometric sequence is -49152, and the eleventh term of an geometric sequence is -3145728 its first term a1= and common ratio r =

The first two terms of an infinite geometric sequence, in order, are 2log2x, log2x, where x > 0. Find r.

7a. The first three terms of an arithmetic sequence are 36, 40, 44, ... (i) Write down the value of d. (ii) Find u8 . 7b. (i) Show that Sn = 2n2 +...

An arithmetic sequence has a as the first term and 2d as the common difference. The sum of the first 50 terms is T. Another sequence, with first term a+d, and common difference 2d, is combined...

Find that serial and give details to me

Please answer as soon as possible!😞 This is for my friend and not for me 😅 Its her exam tomorrow 😕 Thank you do much in advance!😁💓

In other words: Pattern 1= 3 line segments (1 triangle) Pattern 2= 9 line segments (4 triangles) Pattern 3= 30 line segments (16 triangles) etc.......

Help pls for assignment what formula will i use arithmetic or geometric

Nth term of sequence 1, 3, 15, 61, 213 and also 6th term ...thx
