4, 8 , 12 , 16 .....
- This is an arithmetic sequence because there is a common difference of 4 between each term.
- This is a geometric sequence because there is a common ratio of 2 between each term.
Hope it will help.
Answer: x=13
Step-by-step explanation:
(x-5) + x = 21 given
2x-5=21 combined like terms
2x=26 addition property of equality
x=13 division property of equality
Answer:
108
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 16 - 12 = 4, thus
= 12 + (24 × 4) = 12 + 96 = 108
Answer:
9x -2
Step-by-step explanation:
(7x + 3) + (4x - 1) - (2x + 4)
Distribute the minus sign
(7x + 3) + (4x - 1) - 2x - 4
Combine like terms
7x+4x-2x +3 -1-4
9x -2
