For example, b3 = b2 + 2b1 = 1 + 2(1) = 3. In this question, the following facts may be helpful: • A geometric sequence is a sequence in which each term after the first is obtained from the previous term by multiplying it by a non-zero constant called the common ratio. For example, 3, 6, 12 is a geometric sequence with three terms and common ratio 2. • The sum of the first n terms of a geometric sequence with first term a, and common ratio r + 1, equals a

Question
I will leave a like, please show all steps
Transcribed Image Text:The sequence A, with terms a1, a2, a3, . .., is defined by
an = 2", for n >1.
The sequence B, with terms b1, b2, b3, ..., is defined by
bị = 1, b2 = 1, and b, = bn-1+2b,–2; for n > 3.
For example, b3 = b2 + 2b1 = 1+2(1) = 3.
In this question, the following facts may be helpful:
• A geometric sequence is a sequence in which each term after the first is obtained
from the previous term by multiplying it by a non-zero constant called the common
ratio. For example, 3,6, 12 is a geometric sequence with three terms and common
ratio 2.
• The sum of the first n terms of a geometric sequence with first term a, and common
ratio r + 1, equals a ( ).
