Answer:
14. 89
Step-by-step explanation:
since both triangles are similar just different sizes, it can be concluded that angle r is the same as angle z
1st let's calculate r the common ratio:
r = (-20)/4 = (100/-20) = -5
Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank
Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶
Value of nth term = 62,500
N = 5m
<span>n = m+35 </span>
<span>5m = m + 36 </span>
<span>4m = 36 </span>
<span>m = 9 </span>
<span>n = 45 </span>
242.9 . I worked it out on a piece of paper so it might be right .
