#### 10 cm by 20 cmQuestion: A GIS analyst is mapping urban heat zones and records temperature data at 7 different locations, each labeled either H for high heat or L for low heat. How many such 7-character sequences contain at least one instance of two consecutive Hs?
$ a_n $: number of valid sequences of length $ n $ with no two consecutive Hs.
$ a_2 = 3 $: sequences are LL, LH, HL (excluding HH)
= $1,157.63 (rounded to two decimals)
