Step-by-step explanation:
supplentary means they add to 180
so you can make the formula 180 = 10x + 80
then solve for x

Answer:
4095
Step-by-step explanation:
3(4⁰) + 3(4¹) + 3(4²) + 3(4³) + 3(4⁴) + 3(4⁵)
3(4⁰ + 4¹ + 4² + 4³ + 4⁴ + 4⁵)
3(1 + 4 + 16 + 64 + 256 + 1024)
3 * 1365 = 4095
Answer:
The expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
Step-by-step explanation:
Given the sequence
9, 17, 25, 33
a₁ = 9
<em>Determining the common difference</em>
d = 17-9 = 8
d = 25-17 = 8
d = 33-25 = 8
As the common difference between the adjacent terms is same and equal to
d = 8
Therefore, the given sequence is an Arithmetic sequence.
An arithmetic sequence has a constant difference 'd' and is defined by

substituting a₁ = 9, d = 8 in the equation


Therefore, the expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
