Answer:
Step-by-step explanation:
Let us first closely examine the sequence for any mathematical correlation between the terms of sequence.
It is visualized that the series is progressing with addition of increasing even numbers starting with +6 ( +6, +8, +10, +12, +14, +16, +18 …) in the previous term to obtain next terms of the series. This logic continues for entire series.
The given series is:
1 ,7 ,15 ,25 ,37
Starting with first number of the series
1
1 + 6 = 7
7 + 8 = 15
15 + 10 = 25
25 + 12 = 37
37 + 14 = 51
51 + 16 = 67
67 + 18 = 85
The extended series is
1, 7, 15, 25, 37, 51, 67, 85

A circle has an area of 40 square meters. Which answer is closest to the measure of its diameter?
Ok, so i got 144 cubic cubic meters by multiplying 6 by 6 by 4. Tell me if it's correct because i'm not the best at Math, but I checked and rechecked it. <span />
Answer:
Converges
Sum = 20.8333
Step-by-step explanation:
A geometric series has a general formula of:

Where 'a' is the initial term, 'n' is the number of terms, and 'r' is the constant ratio. If |r| < 1 than the series converges.
In this particular case, the initial term is a=25, and each term is being divided by -5, or multiplied by -0.2, so the general form would be:

Since 0.2 < 1.0, the series converges.
The sum of the series is given by:

The sum is 20.8333.
