Answer:
Step-by-step explanation:
<u>Given sequence:</u>
<u>The first term is:</u>
<u>The common ratio is:</u>
- r = 50/10 = 10/2 = 2/0.4 = 5
<u>The formula for the nth term is:</u>
Start by dividing 42 by 1, then 2, then 3, and so on. Only include the ones that produce a whole number.
42 / 1 = 42
42 / 2 = 21
42 / 3 = 14
42 / 6 = 7
42 / 7 = 6 (appears again, so you can stop the process now)
42 = 1 x 42
42 = 2 x 21
42 = 3 x 14
42 = 6 x 7
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
Answer:
x = 2
Step-by-step explanation:
3(x - 1) = 23 - 5(x + 2) ← distribute parenthesis on both sides
3x - 3 = 23 - 5x - 10
3x - 3 = 13 - 5x ( add 5x to both sides )
8x - 3 = 13 ( add 3 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
