Answer 1

Explicación paso a paso:

a) 2,3,4,5,6....

d = 1

A1 = 2

An = A1 + d(n+1)

A23 = 2 + 1 ( 23 + 1 )

= 2 + 24

= 26

A23 = 26

A30 = 2 + 1( 30 + 1 )

= 2 + 31

= 33

A30 = 33

b) 6,8,10,12...

d = 2

A1 = 6

An = A1 + d(n+1)

A23 = 6 + 2( 23 + 1 )

= 6 + 2×24

= 54

A23 = 54

A30 = 6 + 2( 30 + 1 )

= 6 + 2×31

= 68

A30 = 68
