I have no idea what the answer is to this question
Answer: -13, -17, -21
Explanation: Subtract 4 from each term. Do this for 3 terms
Answer:
![\sqrt[6]{z}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7Bz%7D)
Step-by-step explanation:
The denominator of the fractional exponent is the index of the root.
Answer:
50% increase.
Step-by-step explanation:
(New Value - Initial Value)/(Initial Value) * 100 = percentage increase or decrease
(The formula)
Answer:
a1 = 2
d = 3
an = 2 + (n - 1) * 3
a7 = 20
a59 = 176
Steps:
a1 is the initial value (when n equals 1), and since there are 2 crosses, it is 2.
d is the added value to each amount of crosses. And since the second amount is 5 and the third amount is 8, we can determine that each n is adding 3 crosses, therefore making d = 3.
The equation is simply plugging in the values for a1 and d.
A7 is simply plugging in 7 for n in the equation and solving for it. So;
a7 = 2 + (7 - 1) * 3
a7 = 2 + 6 * 3
a7 = 2 + 18
a7 = 20
And same thing as the last for 59 except substitute 59 in for where you put 7;
a59 = 2 + (59 - 1) * 3
a59 = 2 + 58 * 3
a59 = 2 + 174
a59 = 176
