x < - 1
It is a term because it’s a number and letter together
Answer:
this is your test right pls study and answer
The formula is
Sn = a1. 1 - r^n
--------- where r = common ratio and a1 = first term
1 - r
Here we have r = -6 and a1 = -1, and n = 6. So:-
Sum of 6 terms S6 = -1 * 1 - (-6)^6
------------- = 6665
1 - (-6)
