The sequence is defined recursively, with the first term \( c(1) = -20 \) and for subsequent terms:
\[ c(n) = c(n - 1) + 10 \]
To find the second term \( c(2) \):
-
Start with the first term: \[ c(1) = -20 \]
-
Apply the recursive formula to find \( c(2) \): \[ c(2) = c(1) + 10 \] Plugging in the value of \( c(1) \): \[ c(2) = -20 + 10 = -10 \]
Thus, the second term in the sequence is \( c(2) = -10 \).
