Step-by-step explanation:
Given the formula
a(n+1)=an−3
The first term a(1) = 31
<u>For</u><u> </u><u>the</u><u> </u><u>second</u><u> </u><u>ter</u><u>m</u>
a(2)
We have
a( 1 + 1) = a(1) - 3
a(2) = 31 - 3
a(2) = 28
<u>For</u><u> </u><u>the</u><u> </u><u>thir</u><u>d</u><u> term</u>
a(3)
We have
a(2+1) = a(2) - 3
a(3) = 28 - 3
a(3) = 25
<u>For</u><u> </u><u>the</u><u> </u><u>four</u><u>th</u><u> term</u>
a(4)
That's
a(3+1) = a(3) - 3
a(4) = 25 - 3
a(4) = 22
