286
Step-by-step explanation:
Use term formula for +/-
Tn = a + (n-1)d
n= number of term
a= first number in sequence
d= difference between each number

Answer:
1073.38
Step-by-step explanation:
975 × 0.01 = 9.75
9.75 + 975 = 984.75
984.75 × 0.09 = 88.6275
88.6275 + 984.75 = <u>1073.38</u>
Xp + yp = z....for p
p(x + y) = z
p = z / (x + y)
a = b + cp.....for p
a - b = cp
(a - b) / c = p
