Answer:
-1280
Step-by-step explanation:
Given a₁ = -10, n = 8, r =2
Required to find nᵗʰ term.
From the general formula: aₙ= a₁ (r)ⁿ⁻¹
Therefore nᵗʰ = -10(2)⁸⁻¹
= -10(2)⁷
= - 10(128)
= - 1280
Answer: 33
<u>Step-by-step explanation:</u>
The ratio of Adhy's to Ben's is 3:4 so let
Adhy = 3x
Ben = 4x
Since Ben = Adhy + 9
then 4x = 3x + 9
--> x = 9
So, Adhy = 3x = 3(9) = 27
Ben = 4x = 4(9) = 36
*************************************************************
The ratio of Ben's to Clayson's is 3:5
How do we get Ben's ratio of 3 equal to 36? <em>by multiplying by 12</em>
Ben : Clayson
<u>3 x 12</u> <u>5 x 12</u>
36 60
So, Clayson = 60
***********************************************************
The difference between Adhy and Clayson is:
Clayson - Adhy
60 - 27 = 33
