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:
Answer:
Step-by-step explanation:
B/c the bigger triangle is a copy of the smaller we can say
8 / 12 = x / 8
then, solve for x
8(8
/12) = x
(64 *3) 12 = x
192 /12 = x
16 = x
nice, the first answer looks good , then :P
