If an is a5
and
an-1 is a4
then using your recursive formula for an arithmetic sequence
an=an-1 +d
then
a5=a4+d
now, a4 =6 and common difference "d" is d=-11
hence
a5=6 -11
6-11= -5
any questions?
Answer: £5
Step-by-step explanation:
Bole sold the article for 125% while he bought it for 100%.
Bole sold for £7.50 so £7.50=125%
£7.50/1.25=£6
125%/1.25=100%
£6=100% (the cost Bole bought the article with from Iluguru)
Iluguru sold it at 120% so 120% is £6
To find 100% we divide by 1.2
£6/1.2=£5
Iluguru bought article for £5 originally

Answer:
2/3 x (-6) ×5 = -20/
1
= -20
Step-by-step explanation:
Multiple: 2/
3
* (-6) = 2 · (-6)/
3 · 1
= -12/
3
= -4 · 3/
1 · 3
= -4
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-12, 3) = 3.
In words - two thirds multiplied by minus six = minus four.
Multiple: the result of step No. 1 * 5 = -4 * 5 = -20
