A scientist was in a submarine below sea level studying ocean life over the next 10 minutes she went down 58 ft how many feet had she been below sea level if she was 2.5 ft below sea level after she went down

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.

answer: 2 and 1

step-by-step explanation: got this question

so, converting firstly the mixed fractions to improper fractions and then "adding".

if you need just tell me and i will come to the rescue.
