two trains train A and train B weighed a total of 178 tons train A is heavier than train B the difference of their weight is 72 tons what is the weight of each train?​

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.

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

answer: the correct answer is -32
