Please help- I don't know math very well :(

Vanyuwa [196]

$\\ \sf\longmapsto f(x)=4(x-3)$

$\\ \sf\longmapsto f(3)$

$\\ \sf\longmapsto 4(3-3)$

$\\ \sf\longmapsto 4(0)$

$\\ \sf\longmapsto 0$

Here

a_n=7n

$\\ \sf\longmapsto a_{10}=7(10)=70$

d=1/4

a=1/4

$\\ \sf\longmapsto a_4=a+(n-1)d$

$\\ \sf\longmapsto a_4=\dfrac{1}{4}+(3)(\dfrac{1}{4})$

$\\ \sf\longmapsto a_4=1$

$\\ \sf\longmapsto y=2x-8$

$\\ \sf\longmapsto 2x=y+8$

$\\ \sf\longmapsto f(x)=\dfrac{8+y}{2}$

$\\ \sf\longmapsto a_n=n-1$

$\\ \sf\longmapsto 4.5- 4(0.5)$

$\\ \sf\longmapsto 4.5-2$

$\\ \sf\longmapsto 2.5$
