Ruddy has x dollars in his account. He spends $34.56 to buy medicines for his grandmother. If the balance in his account is $265.34, what was the amount in his account before purchase?

$299.90

Step-by-step explanation:

Add the $34.56 back to the $265.34

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
