The sum of half a number and 5 is 55.What is the number?

100

Step-by-step explanation:

1/2*100=50

50+5=55

x = 100

Step-by-step explanation:

1/2x+5 = 55

(2/1) * 1/2x   =   50(2/1)

x = 100

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.
