Sequence Explicit Formula

Given the common difference of the arithmetic sequence. Find the explicit formula.

• a_n = -3n + 3

• a_n = 3n + 3

• a_n = -3n - 3

• a_n = -3n + 3n

Given the common difference and first term. Find the explicit formula.

• a_n= 19 +5n

• a_n= 19 -5n

• a_n= -19 +5n

• a_n= -19 -5n

Given the common difference and first term. Find the 37th term.

• 204

• 195

• 215

• 180

Which formula is used to find the explicit equation for arithmetic sequences?

• a_n = a₁ + d(n-1)

• a_n = a_n-1 + d

Which of the following is the explicit formula for geometric sequences?

• g_n=g_n-1 (r)

• g_n=g₁ (r^n-1)

Find the explicit formula:
-3, -33, -63, -93, ...

• a_n = -3 - 30(n -1)

• a_n = -3 + 30(n -1)

• a_n = -30 - 3(n -1)

• a_n = -30 + 3(n -1)

Find the explicit formula:
-23, -16, -9, -2, ...

• a_n = -23 + 7(n -1)

• a_n = -23 - 7(n -1)

• a_n = 7 - 23(n -1)

• a_n = 7 + 23(n -1)
