Just take n=1,2,3,4,5 respectively to find out the first 5 terms.
First 5 terms = 4,3,2.25,1.69 respectively.
For the 5th partial sum, just add the first 5 terms.
5th partial sum = 10.34
....
First 4 terms : 5,8,11,14 respectively.
Now you need to find the other next 4 terms to find out the 8th partial sum.
17,20,23,26
8th partial sum = 124
Hope this helps:)
11 = C/2-1 + C/2 + C
12 = C/2 + C/2 + C
12 = 4C/2
12 = 2C
C = 12/2
C = 6
Hence, tree A is 2m (3-1), tree B is 3m (6/2) and tree C is 6m
Answer:
5 tricycles, 2 bicycles
Step-by-step explanation:
5•3=15 2•2=4 15+4=19
always start with the largest group and try it out, if it doesn't work, subtract one from the largest group and try again.
Answer: The 18th term is 295.
Step-by-step explanation: By using the arithmetic sequence formula:
a(n): nth term
a(1): first term
n: term position
d: common/constant difference
a(n) = a(1) + (n - 1)d
You should get an equation of a(n) = 6+(18 - 1)17. By following the order of operations, you should receive an 18th term of 295.
