Answer:
49.33
Step-by-step explanation:
To find the 7th term, all you have to do is plug it in the equation.
First n would equal 7 because we are looking for the 7th term.
Now, let's plug everything we know into the equation.
a7 = 2+5 * (7-1)
= 2 + 5 * 6
= 2 + 30
= 32
In conclusion, the 7th term would equal 32.
7 tens=10,10....=70
20 ones=1,1....=20
which sum up to be 90
5 tens=50
13 ones=13
=63
