The common difference is 2
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 = -5
a10 = 13
Substituting n=10 a10=13 and a1 =-5
13 = -5 +d (10-1)
13 = -5 +9d
Add 5 to each side
13+5 = -5+5 +9d
18 = 9d
Divide each side by 9
18/9 = 9d/9
2 =d
Answer:
13 students were fed
Step-by-step explanation:
now first in order to count we will have to turn 3 1/4 into a whole number which means we will have to multiply the denomintor by 3 and add it to the numerator which is 1
4 x 3= 12 ..... 12 + 1 = 13
13/4 and the denominator always stays the same
and now to count we will have to divide 13/4 divided by 1/4
now instead of dividing you can just multiply them by switching the denominator and numerator 1/4 to 4/1
13/4 x 4/1
52/4
13
