Write a recursive formula for the sequence 7, 4, 1, –2, –5, then find the next term. (1 point) an = an–1 – 3, where a1 = –8; 7 an = an–1 – 3, where a1 = 7; –8 an = an–1 + 3, where a1 = –3; 22 an = an–1 + 3, where a1 = 7; –8

, where

The next term is -8.

Step-by-step explanation:

The given sequence is 7, 4, 1, –2, –5, ................

Here, the first term is

The second term is

The difference =

Similarly,  

and so on.

Therefore, the recursive formula for the above sequence will be given by :-

, where d is the common difference.

Since , d=-3

, where

The next term of the sequence is

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
