11th term is 10240
Step-by-step explanation:
- Step 1: Given the sequence 10,20,40. So a(1) = 10, common ration, r = 20/10 = 2 Find the 11th term using the nth term formula, a(n) = ar^n-1
⇒ a(11) = 10 × 2^10 = 10 × 1024 = 10240
If you have two terms in a sequence, then a term decreased by the previous term=common difference
so
30 and 27
27 decreased by 30 is -3
the common differce is -3
Answer:
that one over there
Step-by-step explanation:
Answer:
reciprocal of 1 is 1 and 1/9 is 9.
A=7d+13
A=7(4)+13
A= 28+13
A=41
