A) If the 5th term of an A.P. is double the 7th term, show that the sum of the 17 terms zero.​
gayaneshka [121]

Answer:

see explanation

Step-by-step explanation:

The nth term of an AP is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₅ is double a₇ , then

a₁ + 4d = 2(a₁ + 6d) , that is

a₁ + 4d = 2a₁ + 12d ( subtract a₁ from both sides )

4d = a₁ + 12d ( subtract 12d from both sides )

- 8d = a₁

The sum of n terms of an AP is

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ] , substitute values

S_{17} = \frac{17}{2} ( 2(- 8d) + 16d)

     = 8.5(- 16d + 16d)

     = 8.5 × 0

     = 0

Equation & Answer:

134.4 ÷ 5.6 = 24


17. 32 miniature bottles can be made from the large bottle of ketchup.

Equation & Answer:

198.4 ÷ 6.2 = 32


20. -3 + -8 = -11


-3 + 8 = 5


3 + -8 = -5


-9 + 4 = -5


-6 + -1 = -7


-8 + 9 = 1


Negatives plus negatives:

When there are two negative numbers together and the equation has + sign in it, the + sign changes to be a - sign.


21. 42 + -56 = -14


22. -49 + -17 = -66


Hope this helped in some way,
