(2x - 1)2 = 49
What are the solutions to this?

x = 51/4 or x = 12.75

Step-by-step explanation:

(2x - 1)2 = 49

4x - 2 = 49

4x = 49 + 2

4x = 51

x = 51/4 or x = 12.75

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.
