In this study, two groups of subjects were formed to compare the effects of psilocybin. One
group was treated with a high dose of psilocybin. The other group was treated with a
comparison compound (control group). The subjects of either group did

Geometric sequences have a first term called t1 or a and a _ _.
This _ _ must always take on value
6.2 Arithmetic Series
When terms of an arithmetic sequence are added, the result is known as an arithmetic
series.
For example:
3, 5, 7, 9, 11 is an arithmetic sequence (first term: _ & common difference: _)
3 + 5 + 7 + 9 + 11 is an arithmetic series (fir
