If arithmetic, then there is a common difference
if geometric, then there is a common ratio
to find the common ratio or difference
if you subtract successive terms from each other, they should have the same result if it is aritmetic
if you divide successive terms by each other, they should have the same result if it is geometric
2,3 and 5
3-2=1
5-3=2
2≠1
not aritmetic
3/2=1.5
5/3=1.66666
1.5≠1.6666
not geometric
she is wrong
Answer:
$15.
Step-by-step explanation:
90-75=15, which is the difference between the two. Hope this helps.
Answer:
19th term = ar^18
19th term = 774,840,978
Step-by-step explanation:
First term, a = 2
Common ratio, r = 3
nth term of a geometric sequence = ar^(n-1)
19th term = ar^(19-1)
19th term = ar^18
= 2 × 3^18
= 2 × 387,420,489
= 774,840,978
19th term = 774,840,978
x = ×-3/4
because you hace the variable x and you do not know the number of fruit snacks he ate and you need to have the same variables to properly find the answer.
22 I think it’s probably wrong but I tried
