Answer:
(a) 34.
(b) Yes.
Step-by-step explanation:
The first term is 3(1)^2 + 1 = 4 ( where k = 1).
The sum of 2 terms = 3(2)^2 + 2 = 14.
The sum of 3 terms = 3(3)^2 + 3 = 30.
The sum of 4 terms = 3(4)^2 + 4 = 52.
So the first 4 terms are 4, 10, 16 and 22 . - increasing by 6.
The common difference is 6 so it is an arithmetic sequence.
The 6th term = a1 + d(n - 1)
= 4 + 6(6-1)
= 34.
Answer:
2.50 c+7.50 d=182.50
2.5 c+7.5 d= 182.5
c+3 d=73
c+d=37
subtract
2d=36
d=18
c=37-18=19
number of cats=19
