Find the oth term of the geometric sequence 9, -18, 36, ...

2304

Step-by-step explanation:

Given :-

And we need to find out the 9th term of the sequence. Here firstly we should find the Common Ratio and then we can substitute the respective values in the formula to find the nth term of a geometric sequence .

Common Ratio :-

CR = -18÷ 9 = -2

The 9 th term :-

T_n = arⁿ - ¹

T_9 = 9× (-2) ⁹ - ¹

T_9 = 9 × (-2)⁸

T_9 = 9 × 256

T_9 = 2304

Hence the 10th term is 2304.

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.
