Which one is the correct one

kenny6666 [7]

Step-by-step explanation:

Sum of opposite angles are supplementary,

x + 60 + 3x = 180

4x + 60 = 180

4x = 180 - 60

4x = 120

x = 120 / 4

x = 30

Write the first four terms of the sequence defined by An=20-30(n-1)

monitta

The first four terms of sequence is 20, -10, -40, -70

Solution:

Given that we have to find the first four terms of sequence

Given recursive formula is:

$a_n = 20 - 30(n-1)$

To find the first term, substitute n = 1

$a_1 = 20-30(1-1)\\\\a_1 = 20-30(0)\\\\a_1 = 20$

Thus the first term of sequence is 20

To find the second term, substitute n = 2

$a_2 = 20-30(2-1)\\\\a_2 = 20-30(1)\\\\a_2 = 20-30\\\\a_2 = -10$

Thus the second term of sequence is -10

To find the third term, substitute n = 3

$a_3 = 20-30(3-1)\\\\a_3 = 20-30(2)\\\\a_3 = 20-60\\\\a_3 = -40$

Thus the third term of sequence is -40

To find the fourth term, substitute n = 4

$a_4 = 20-30(4-1)\\\\a_4 = 20-30(3)\\\\a_4 = 20-90\\\\a_4 = -70$

Thus the first four terms of sequence is 20, -10, -40, -70
