A sub 2 is equal to 11

a2=−9
A sub 2 is equal to negative 9

a2=12
A sub 2 is equal to 12

a2=2

Answer 1

To find the second term of the sequence \( a_2 \), we can use the recursive formula given:

1. The first term \( a_1 = 22 \).
2. The recursive formula for the sequence is \( a_n = a_{n-1} - 10 \).

Using this formula to find the second term \( a_2 \):

\[ a_2 = a_1 - 10 \] \[ a_2 = 22 - 10 \] \[ a_2 = 12 \]

So, the second term of the sequence is \( a_2 = 12 \).

The correct response is: a2=12
A sub 2 is equal to 12.
