Answer:
Step-by-step explanation:
t1 means a1 and t7 means a7
a+(n-1)d=an
a+(1-1)d=4
so we get a as 4
<u><em>a=4</em></u>
a+(n-1)d=an
4+(7-1)d=22
4+6d=22
6d=22-4
d=18/6
<u><em>d=3</em></u>
8*8 = 64
64-8 = 56
Answer is 56
Keith started with 44 cards.
So we need to work backwards.
After his dog ate half his collection, he had 25 cards.
To reverse that, you need to multiply 25 by 2.
25×2=50
If he bought 6 new cards that day, then he started with 6 cards less.
So you have to subtract 6 from 50.
50-6=44
