Finding terms of an arithmetic sequence with a recursive formula a1 =12 an= an-1+7

Mathematics
1 answer:
Basile [38]3 years ago

Hey there!!

Recursive formula :

... a( n ) = a ( n - 1 ) + 7

The first term is 12

To find the second term, we will need to substitute 2 in place of ' n '

2 term :

... a( 2 ) = a ( 2 - 1 ) + 7

... a( 2 ) = a( 1 ) + 7

We know a( 1 ) = 12

... a( 2 ) = 12 + 7

... 19 is the second term and we will need to use this to find the other terms.

Hope my answer helps!

6(x-5) = 5(x+5)
Mariana [72]

Part 1:

6(x-5) = 5(x+5) (x = 55)

4y + 2 (-3 + 2y) = 1-y (x = 7/9)

Part 2:

4(a-6) = 8a - (4a-24) (No Solution)

4(2x-8) = 8(x-8) (No Solution)

2(3x-3) = -6x-6 (Identity (x = 0))

Answer: (3, -1)

Step-by-step explanation:

Reflecting over y = -x maps (x, y) \longrightarrow (-y, -x).

So, F(1,-3) \longrightarrow F'(3, -1)
