Mathematics
1 answer:
NikAS [45]2 years ago
5 0

Answer:

2, - 2, - 6, - 10, - 14

Step-by-step explanation:

To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the expression.

n = 1 : 6 - 4(1) = 6 - 4 = 2

n = 2 : 6 - 4(2) = 6 - 8 = - 2

n = 3 : 6 - 4(3) = 6 - 12 = - 6

n = 4 : 6 - 4(4) = 6 - 16 = - 10

n = 5 : 6 - 4(5) = 6 - 20 = - 14

Thus the first 5 terms are 2, - 2, - 6, - 10, - 14

|j|=|2j+3| please help me
Softa [21]
Simplifying
j = (2j + 3)

Reorder the terms:
j = (3 + 2j)

Remove parenthesis around (3 + 2j)
j = 3 + 2j

Solving
j = 3 + 2j

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-2j' to each side of the equation.
j + -2j = 3 + 2j + -2j

Combine like terms: j + -2j = -1j
-1j = 3 + 2j + -2j

Combine like terms: 2j + -2j = 0
-1j = 3 + 0
-1j = 3

Divide each side by '-1'.
j = -3

Simplifying
j = -3
