Checking if the sequence is an arithmetic sequence
7 - 1 = 6
13 – 7 = 6
Therefore the sequence is arithmetic, with a_0 = 1 and d = 6
a_n = a_0 + (n-1)d
a_30 = 1 + (29)(6)
= 175
Therefore the 30th term is 175.
Answer:
4 minutes
Step-by-step explanation:
2 will cook together for 1 minute. and it will take an additional 2 minutes to cook the 3rd pancake.
The first one is the second one. t(n)=20n+480
Question 4: is the first one t(n)=8n+15
Just divide as you normally would but 1 or 2 numbers at a time
The answer would be 1/3 right?
