Answer:
Step-by-step explanation:
<span>a_n = a_1 + (n-1)d
a_n = 4 + 3(n-1) = 3n + 1
So the 30th term is a_30 = 3*30 + 1 = 91</span>
<span>1/5(2x-15) + (3/5)x = 4 1/4
</span><span>x*2/5 - 15/5 + x*3/5 = 4 1/4
</span><span>x*2/5 - 3 + x*3/5 = 4 1/4
</span><span>x*(2/5+3/5) - 3 = 4 1/4
</span><span>x*(5/5) - 3 = 4 1/4
</span>1*x - 3 = 4 1/4
<span>x= 4 1/4 + 3
</span><span>x= 7 1/4 </span>
