This is an arithmetic sequence because each term is 1/8 more than the previous term. This is called the common difference and it is what defines an arithmetic sequence.
a(n)=a+d(n-1), where a is 1st term, d is common difference, and n it term #
In this case:
a(n)=3.25+0.125(n-1) or more neatly...
a(n)=3.125+0.125n
a(5)=3.75
set equal to 0
factor out the
what 2 numbers multiply to get -2 and add to get -1? -2 and 1
set each equal to 0
x=0
x-2=0
x=2
x+1=0
x=-1
so the zeroes of the function are at x=-1, 0, 2
Answer:
i think its A sorry if wrong
Step-by-step explanation:
Step 1. 2 ^n * 2 ^ n+2 * 2 The exponent is 1
step 2. 2 ^n * 2 ^n+2 * 2^1 Calculate the product
step 3. 2^n + n + 2 + 1 Collect the like terms and Calculate the sum
step 4. 2^2n + 3
answer: 2^2n + 3
hope this helps :)
