write a general term to find the number of flowers in the nth row when the first row has 42 flowers, 2nd has 40 flowers the 3rd has 38 flowers..etc..
-
assuming n= what row you are in. number of flowers = 44-2n
-
a=42
d=2
an=a+(n-1)d=42+(n-1)2
That is you can find the number of flowers in the nth row is given by 42+(n-1)2
d=2
an=a+(n-1)d=42+(n-1)2
That is you can find the number of flowers in the nth row is given by 42+(n-1)2
