Answer:
95
Step-by-step explanation:
Being a sum of two elements that include units and tens, we can make the sums of the units first, and then add the tens together.
So, if we have 45+50, we can first separate the units: 5 + 0 =5
Then, we separate the tens: 4+5=9
Now, we only join the sums of the units and tens, and that will be the end result. 95
Answer: common difference is 14
Step-by-step explanation:
a,a+d,a+4d
7,7+d,7+4d
(7+d)/7=(7+4d)/(7+d)
(7+d)(7+d)=7(7+4d)
49+14d+d^2=49+28d
d^2-14d=0
d(d-14)=0
d=0 or d-14=0
d=14
