The sequence above is geometric progression.
The nth term of such sequence is given by;
Tn = ar∧(n-1),
Where a⇒first term and
r⇒common ratio
So, 1st term = 5×1.25∧(1-1) = 5×1.25∧0 =5
2nd term = 5×1.25∧(2-1) = 5×1.25 = 6.25
3rd term = 5×1.25∧(3-1) = 5×1.25² = 7.8125
4th term = 5×1.25∧(4-1) =5×1.25³ = 9.765625
5th term = 5×1.25∧(5-1) = 5×1.25∧4 = 12.20703125
6th term = 5×1.25∧(6-1) = 5×1.25∧5 = 15.25878909
Answer:
I think it's x=-12 for the buttom one
Step-by-step explanation:
I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1
so take the 25 away from 1. to do that we need to do the opisite of +
2x + 25 = 1
1 - 25 = -24
rewrite
2x = -24
take the 2 away. oppisite of mulitplication is division. so divide 2 by -24
-24 divided by 2 = -12
Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D
