There are 3 eighths in 0.25
The formula of arithmetic sequence is
an = a₁ + d(n - 1)
Then we need to find the formula to determine n. I reverse the equation so the 'n' will be on the left side.
a₁ + d(n - 1) = an
Then I move all the terms on the left one by one to the right side except n
a₁ + d(n - 1) = an
d(n - 1) = an - a₁
n - 1 = (an - a₁)/d
n = 1 + (an - a₁)/d
This is the formula to solve n
n = 1 + (an - a₁)/d
Answer:
I believe the answer is 5x = 14
Answer:
-2a^5 + 4a^4 + 5a^3 + 2/3 a
Step-by-step explanation:
Standard form for an expression is written in descending order according to the exponent on the variable. The term with the highest exponent is written first.
2/3 a + 5a^3 + 4a^4 - 2a^5 becomes -2a^5 + 4a^4 + 5a^3 + 2/3 a
