<span>a1= (which is the first term.)
 to find the 2nd term you plug in 2 for (an) in the formula given to you. =-4(2-1)^2 *remember an represents the term u are looking for *
 now you start to solve it
 -4(2-1)^2
 -4 (1)^2
.
-4^2
= 16
 so your first two terms are 2 and 16 .</span>

Remark
It looks like all you want is question 6. If that is the case, there are two ways to do it.
Algebra
<u>First answer</u>
abs(b - 22) = 5      Equate to + 5
b - 22 = 5              Add 22 to both sides.
b = 5 + 22
b = 27
<u>Second Answer</u>
Equate to - 5
b - 22 = -5
b = 22 - 5
b = 17
Method Two
<u>Graph the question</u>
The graph y = abs(b - 22) is shown below in red. 
The values of y when y =5 are shown in blue.
