Write a strategy : Two players play a game on a blackboard. The first player begins by writing the number 2. Then, on each players turn, they first select a whole number smaller than the number written on the blackboard. Then, they replace the number on the board with the sum of the previous number and their selected number. The player who writes the number 1000 wins.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
