Step-by-step explanation:
The nth term of an AP is
= 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
= [ 2a₁ + (n - 1)d ] , substitute values
= ( 2(- 8d) + 16d)
= 8.5(- 16d + 16d)
= 8.5 × 0
= 0
<span>2, 8, 32,128
8/2 = 4
32/8 = 4
128/32 = 4
Each number is being multiplied by 4.
128*4 = 512
512*4 = 2048
512 and 2048 are the next two numbers.</span>
I think the answer is 616m^3
The quotient is 4x-3. Hope this helps you:)
