Yea I'm pretty sure it's all right not 100% positive
The fifth term in the sequence would be 161.
Step-by-step explanation:
We have to find the fifth term in the sequence 
Given that
a1 = 1 (that is the first term)
If we follow the formula, the value of every term depends on the value of immediate lower term. Therefore, the a2 can be calculated by putting 2 in place of n in above equation


as a1 = 1

Similarly,


as a2 = 5

and


as a3= 17

and


as a4 = 53

Therefore, the fifth term in the sequence would be 161.

Answer:
1. 2.90$
2. No, because that would be 2.30$
3. I don't know what it means by that but maybe 10 quarters and 4 dimes.
If there is more to the questions this isnt it.
Step-by-step explanation:
I would assume the answer would be a. 18 assuming your trying to find the entire value of a triangle but have a missing value
Hey there!!
They're called Inverse operation. Such as *multiplication and division* and *addition and subtraction*
