2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6
<span>Sometimes, rather than </span>finding<span> the next number in a linear </span>sequence, you want tofind<span> the 41</span>st<span> number, or 110</span>th<span> number, say. Writing out 41 or 110 numbers takes a long time, so you can use a general rule. To </span>find<span> the value of any </span>term<span> in a </span>sequence, use the nth term<span> rule.</span>
