Find the second, fourth, and tenth terms of the sequence described by the rule.
A(n)=2+ (n-1)(7)

a(2) = 9

a(4) = 23

a(10) = 65

Step-by-step explanation:

a(2) = 2 + (2 - 1)(7)

= 2 + 1(7)

= 2 + 7

= 9

a(4) = 2 + (4 - 1)(7)

= 2 + 3(7)

= 2 + 21

= 23

a(10) = 2 + (10 - 1)(7)

= 2 + 9(7)

= 2 + 63

= 65
