To find this, you would plug in the 6 in place of n. h(n) = 3n is now equal to h(6)=3n therefore h= 18
Answer:
Step-by-step explanation:
Answer:
21/2
Step-by-step explanation:
(x-8)/5=2/4
step 1 you simplify if you can to make it easier
(x-8)/5=1/2
step 2 multiply each side by 5
x-8=5/2
step 3 add each side by 8
x=5/2+8
16/2+5/2=21/2
x=21/2
Step-by-step explanation:
Marked price (MP) = x
Selling Price after discount (SP after discount)
= Rs. 1350
Discount rate = 25%
Now
SP after discount = MP - discount % of MP
1350 = x - 25 % of x
1350 = x - x / 4
1350 = 3x / 4
1350 * 4 =3x
5400 / 3 = x
Therefore x = Rs. 1800
The marked price is Rs. 1800
ANSWER
EXPLANATION
The given sequence is
3,-5,-13,.....-229.
The first term of this sequence is
a_1=3
There is a common difference of
The last term of this sequence is -229.
The nth term of this sequence is given by:
We use the last term to determine the number of terms in the sequence.
Divide through by -8;
Hence there are thirty terms in the sequence.
The sum of the first n terms is given by:
The sum of the first 30 terms is given by:
