2) What is 18th term in this sequence: 45, 49, 53, 57,
1 answer:
Answer:
a₁₈ = 113
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 49 - 45 = 53 - 49 = 57 - 53 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 45 and d = 4, then
a₁₈ = 45 + (17 × 4) = 45 + 68 = 113

Alright, lets get started.
Suppose Francine made number of baskets = x
As given in question, Jane scored 4 times as many as Francine.

Dividing 5 in both sides
x = 4
Means Francine made number of baskets = 4
Hence Jane made number of baskets = : Answer

Charges per minute = $1.25
Let,
t be the number of minutes raymond was on Trampoline
Total cost for session = entrance fee + Charges per minute * No. of minutes
1.25t+7=43.25 can be used to determine the number of minutes that Raymond was on the trampoline.
