The coefficient C-term is 1 in problem. The coefficient is the number before the variable of said equation. Example, the coefficient of X for thus problem 4x-4y is 4 the number BEFORE the variable, never variable itself it won’t ever be 4x
So after 100 its 105,112,119...........994
x=7(multiples of what we're finding), y=105(where we start from after 100), a multiplied by z=994
we have to find z
994=105+(z-1)7
994-105=7z-7
889+7=7z
896=7z
z= 128
First count the fully shaded boxes than count each half knowing two halfs equal one
1)32
2)22
3)22
4)12
Answer:
a(n) = -351+8(n-1)
Step-by-step explanation:
This is an arithmetic sequence. Each new term is equal to the sum of the previous term and 8.
The expression you want is a(n) = -351+8(n-1)
Just add them together
9 + 12 = 21
