Math Sequence, Find The Specific Term Of Each Arithmetic Sequence..

Math sequence, find the specific term of each arithmetic sequence..

 

1. An = A1+(n-1)d

A8 = 2 + (8-1) 3

A8=2+(8)3

A8=2+24

A8=28

2. A²¹=3+(21-1)2

=3+(20)2

=3+40

A²¹=43

3. A51=1+(51-1)3.1

=1+(50)3.1

=1+155

A51= 156

4. A²³=-11+(23-1)4

=-11+(22)4

=-11+88

A²³ =77

The rest are all up to the others haha. I enjoyed answering though
