What is the 23rd term of this pattern: 7, -21, 63, -189,.. and determine if it’s arithmetic or geometric ! Please answer this !!
iVinArrow [24]

ANSWER

a_{23} =  219667417263

The pattern is geometric.

EXPLANATION

The given pattern is:

7, -21, 63, -189,..

We can see from the pattern that,

r =  \frac{ - 189}{63}  =  \frac{63}{ - 21}  =  \frac{ - 21}{7}  =  - 3

Since there is a common ratio of -3, the pattern is geometric.

The first term of this pattern is

a_1=7

The nth term of the pattern is given by the formula:

a_n = a_1 {r}^{n - 1}

To find the 23rd term, we put, n=23, the first term and the constant ratio.

a_{23}= 7{ (-3 )}^{23 - 1}

a_{23}= 7{ (-3 )}^{22}

a_{23} =  219667417263

Ann can buy either a pair of jeans or shoes with the allowance she saved up. What is the opportunity cost if she buys the jeans?
Irina-Kira [14]
The opportunity cost that Ann is going to have if she buys the pair of jeans is the chance to buy the pair of shoes with her allowance. She exchanged her opportunity of buying the shoes by buying the pair of jeans. This is the opportunity cost because the potential of losing the alternative (shoes) happened by purchasing the other.
