Answer:
175
Explanation:
1. an (any term) = 27
2. a1 (first term) = -7
3. d (common difference) = 7
• Use the explicit formula:
an = d(n - 1) + a1
a27 = 7(27 - 1) - 7
- Subtract inside the parenthesis ():
a27 = 7(26) - 7
- Distribute:
a27 = 182 - 7
- Subtract:
a27 = 175
Should be a!
26^2 - 22^2 = 192, take the sqrt of that C:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3^3+14*y-(25*y-13)-(y+7*y-9*y)=0
Equation at the end of step 1
((3³ + 14y) - (25y - 13)) - -y = 0
Pull out like factors :
40 - 10y = -10 • (y - 4)
Equation at the end of step3:
-10 • (y - 4) = 0
STEP4:
Equations which are never true:
Solve : -10 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
Solve : y-4 = 0
Add 4 to both sides of the equation :
y = 4
