Question

consider the arithmetic sequence 6,10,14... find the algebraic expression and the 10th term of a sequence​

Answer 1

GIVEN:

• a = 6
• d = 4

TO FIND:

• 10th term

SOLUTION:

Since we need to find the 10th term, n = 10.

an = a + (n - 1) d

a10 = 6 + (10 - 1) 4

a10 = 6 + 9 x 4

a10 = 6 + 36

a10 = 42

Therefore, the 10th term is 42.
