For each sequence given below, find a closed formula for an, the nth term of the sequence (assume the first terms here are always a0) by relating it to another sequence for which you already know the formula.
−1,0,7,26,63,124,…
an=(n^3)-1
−1,1,7,17,31,49,…
an=2n^2-1
0,10,30,60,100,150,.....
an=10*((n(n+1))/2)
2,3,6,14,40,152,…
an=
The first three are correct I can't figure out the
last one.
