Answer: 742
<u>Step-by-step explanation:</u>
The given sequence {27, 31, 35, ... } provides the following information:
- the first term (a₁) = 27
- the difference (d) = 4
We can use the information above to find the explicit rule of the sequence:
We can use the explicit rule to find the 14th term (a₁₄)
Next, we can input the first and last term of the sequence into the Sum formula:
