Answer:
youngest=115
middle=150
elder=230
Step-by-step explanation:
let the youngest be x
the middle will be x+35
the oldest will be 2x
x+x+35+2x=495
4x+35=495
4x=495-35
4x=460
x=115
since the youngest is x,the money he will receive is $115.
the middle will be x+35 which is equal to 115+35=$150.
lastly the oldest will be 2x which is equal to 2×115=$230.
This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
The missing factor would be (n+2)... If you wanted to understand it, you simply solve 4n^2+9n+2 which gives you (4n+1)(n+2).
Answer:
<h2><em><u>62</u></em></h2>
Step-by-step explanation:
<em>Here</em><em>,</em>
x + 118 = 180. <em>[</em><em>Since</em><em> </em><em>Supplementary</em><em> </em><em>Angle</em><em>]</em>
=> x = 180 - 118
=> <em><u>x = 62 (Ans)</u></em>
