Question

The first term of a pattern is 509. The pattern follows the "subtract 7" rule. Which number is a term in the pattern?

A:516
B:500
C:495
D:464

Answer 1

C

Explanation:

first fine the nth term

a+(n-1)d

509+7n+7

516-7n

then equate the ans to the nth term

495=516-7n

7n=516-495

7n= -21

n= -3
