find the first four (4) terms of the sequence if an=an-1-4 and a1=3.

a.
3, 7, 11, 14
b.
–4, –1, 2, 5
c.
3, –1, –5, –9
d.
7, 3, –1, –5

U have an arithmetic sequencean = a1 + (n - 1) * d

an = a1 + (n - 1) * d
a1 = first term = 3
n = term to find
d = common difference = -4

so basically, ur adding -4 to each term to get to the next one
starting at 3
3 - 4 = -1
-1 - 4 = -5
-5 - 4 = -9

so ur sequence is { 3,-1,-5,-9 }
