The rate of change is 4 so your answer would be D. 4
Answer:
The Answer is: The first number is 15 and the second one is 7.
Step-by-step explanation:
Let f = first number and s = second number
The difference between the two is 8:
f - s = 8
f = 8 + s
Twice the first number plus three times the second number is 51:
2f + 3s = 51
Substitute:
2(8 + s) + 3s = 51
16 + 2s + 3s = 51
16 + 5s = 51
5s = 51 - 16
5s = 35
s = 7, the second number
Find f:
f = 8 + 7 = 15, the first number
Proof:
f - s = 8
15 - 7 = 8
8 = 8
Hope this helps! Have an Awesome Day!! :-)
Let starting term, a = 9
Also let a =
So,
= 9
= 15
= 21
-
= 6
-
= 6
∴ this is an arithmetic sequence.
We need to formulate a rule of the form:
= a + (n - 1)d
where n = the
term
So, let n = 32
= 9 + (32 - 1)6
= 9 + 31 x 6
= 9 + 186
= 195
If I have calculated correctly, the 32nd term shoud be 195.
PEMDAS.....parenthesis, exponents, multiplication/division, addition/subtraction
so step 2 is solving the exponents <==
