Answer:
solution given a-d ,a, a+d, a+2d are in A.P
according to the question
sum of 4 terms =12
a-d+a+a+d+a+2d=12
4a+2d=12
2a+d=12/2
d=6-2a
again
3rd + 4rt term =14
a+d+a+2d=14
2a+3d=14
substituting value of d
2a+3(6-2a)=14
2a+18-6a=14
18-14=4a
a=4/4=1
again
d=6-2×1=4
first term =a-d=1-4=-3
second term =a=1
third term =a+d=1+3=4
forth term =a+2d=1+3×2=7
The answer is 2.5 yards and 90 inches?
Observing there is a difference of +8 between each f(x).
The slope of this sequence is 8.(y2-y1)/(x2-x1)
Using the point slope equation,
y-y1 = m(x-x1) yields
y = 8x -4 as the answer.
