A₅ = 1/16  and r= 1/4

Let see how to build up this formula that is going to give that term of rank n

1st term =a₁ = To be calculated

1st a₁   = a₁  x  r°
2nd a₂  = a₁  x  r¹
3rd a₃  =  a₁  x  r²
4th a₄   = a₁  x  r³
5th a₅   = a₁  x  r⁴
.......................
.......................
nth : a(n) = a₁  x r⁽ⁿ-¹)
Note when that the subscript of a is the same as the exponent mines 1

We know the ratio r =1/4 & the fifth term, a₅ =1/16 (given). Now let's apply the formula to calculate the unknown a₁.

a(n) = a₁  x r⁽ⁿ-¹) ==>a₅ = a₁ x (1/4)⁽⁵⁺¹⁾ ===> 1/16 = a₁ x (1/4)⁴
1/167 = a₁ (1/256) ==> a₁ =16 & the formula becomes
a₅ = 16(1/4)⁴

Can some one help thanks

Answer:

y = 8

Step-by-step explanation:

First substitute x with 6 in the equation

2y + 1/3(6) = 18

Multiple 1/3 with 6, which is 2

2y + 2 = 18

Solve the equation by subtracting 2 from both sides

2y + 2 = 18

    - 2     - 2

You get 2y = 16, so you divide 2 frm both sides

You get y = 8

S = ut+ 16t²<br>Find the value of s when u = 2 and t = 3.​
Fed [463]

Answer:

<h2>150</h2>

Step-by-step explanation:

Given,

u = 2

t = 3

Now, Finding the value of s

s = ut \:  + 16 {t}^{2}

Plugging the values of u and t

s = 2 \times 3 + 16 \times  {( 3)}^{2}

Calculate

s = 2 \times 3 + 16 \times 9

s = 6 + 144

Calculate the sum

s = 150

Hope this helps ..

Good luck on your assignment..
