H(1)=-17 h(n)=h(n-1)*0.2 find an explicit formula for h(n).

  h(n) = -17·0.2^(n-1)

Step-by-step explanation:

The explicit formula for a geometric sequence with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

Your sequence h has first term a1 = -17 and common ratio r = 0.2. Then the explicit formula is ...

  h(n) = -17·0.2^(n-1)

1.8k-5+6.1k+3.5+k+1.5=180

Step-by-step explanation:

1.8k-5+6.1k+3.5+k+1.5=180

1.8k+6.1k+k-5+3.5+1.5=180

8.9k=180

k=180/8.9

Hope this helps plz hit the crown :D
