Question

Suppose that I sequences defined as follows. List the 1st 4 terms of the sequence. BRANLIEST ASAP TY!​

Answer 1

The first four terms are -6, -7, -9 and -13.

Step-by-step explanation:

• Step 1: Given first term, a(1) = -6 and the nth term, a(n) = 2a(n-1) + 5. FInd the first four terms.

⇒ a(1) = -6

⇒ a(2) = 2a(1) + 5 = 2 × -6 + 5 = -12 + 5 = -7

⇒ a(3) = 2a(2) + 5 = 2 × -7 + 5 = -14 + 5 = -9

⇒ a(4) = 2a(3) + 5 = 2 × -9 + 5 = -18 + 5 = -13
