Answer:
The explicit formula

The recursive formula
for 
if 
Step-by-step explanation:
If a sequence is arithmetical then the difference between any of its consecutive terms will be constant
3, 3.25, 3.5, 3.75,

The difference between the consecutive terms remains constant so the sequence is arithmetic.
The explicit formula for an arithmetic sequence is:

Where d is the constant difference between the terms.

is the first term of the sequence.

So

Finally, the recursive formula is:

Answer:
$8.90
Step-by-step explanation:
((2)(2.90))+(3.10)= $8.90
Answer:
7) Mean = 48 8) Mean = 59.6 9) Mean = 31.6 10) Mean = 42.1
Median = 47.5 Median = 61 Median = 32 Median = 40
Mode = 72 Mode = 90 Mode = 46 Mode = 51
Range = 66 Range = 79 Range = 34 Range = 51
Step-by-step explanation:
Answer: 5/7
Step-by-step explanation:
Just take the square root of the top and the bottom. Square root of 25=5 and the square root of 49=7, so the square root of 25/49=5/7
Is this the whole equation?
Step-by-step explanation:
Cuz if not we need the whole question
