Answer:
1. an=a1+(n-1)d
an=20+(37-1)(4)
an=20+(36)(4)
an=20+(144)
an=164
2. an=a1+(n-1)d
an=-3+(12-1)(2)
an=-3+(11)(2)
an=-3+22
an=19
3. an=a1+(n-1)d
an=4+(17-1)(3)
an=4+(16)(3)
an=4+48
an= 52
4. an=a1+(n-1)d
an=6+(11-1)2/3
an=6+(10)(2/3)
an=6+20/3
an= 38/3
5. an=a1+(n-1)d
an=16+(20-1)(3/20)
an=16+(19)(3/20)
an=16+57/20
an= 377/20
6. an=a1+(n-1)d
a31=26+(31-1)(-6)
a31=26+(30)(-6)
a31=26-180
a31= -154
7. an=a1+(n-1)d
a13=317+(13-1)(-4)
a13=317+(12)(-4)
a13=317-48
a13= 269
8. an=a1+(n-1)d
a9= 40+(9-1)3
a9=40+(8)(3)
a9=40+24
a9= 64
9. an=a1+(n-1)d
a25=40+(25-1)3
a25=40+(24)(3)
a25= 40+72
a25= 112
10.an=a1+(n-1)d
a11= -29+(11-1)(-5)
a11= -29+(10)(-5)
a11= -29+(-50)
a11= -79
