the equation is,
a_n = a_(n–1) + 3 * n + 2
Substituting the values
for day 4, <span>
<span>20 + 3*4 + 2 = 34<span>
Thus the equation is correct</span></span></span>
Therefore to calculate
for a_n at n = 7 or a_7, we must calculate a_5 and a_6 first.
a_5 = 34 + 3*5 + 2 = 51
a_6 = 51 + 3*6 + 2 = 71
Hence,
a_7 = 71 + 3*7 + 2 = 94
