Question

Please help i need this answer for my end of course test

Answer 1

Option B

The second term of sequence is -9

Solution:

Given that,

$a(1)= -13\\\\a(n) = a(n-1) + 4$

We have to find the second term of sequence

To find the second term of sequence, substitute n = 2 in given recursive formula

Plug in n = 2 in above equation

$a(2) = a(2-1) + 4\\\\a(2) = a(1) + 4$

Substitute a(1) = -13

$a(2) = -13 + 4\\\\a(2) = -9$

Thus the second term of sequence is -9
