Question

What is the eleventh term in the sequence 17, 24, 31, 38…?

Answer 1

87

Step-by-step explanation:

This is an arithmetic sequence with common difference: 7 and first term: 17

Arithmetic sequence:

a + (n - 1)d where n is term position, d is difference, a is first term

17 + (n - 1)7

7n + 10

The eleventh term:

7n + 10

7(11) + 10

77 + 10

87

Answer 2

To Find :-

• Eleventh term of the sequence.

Solution :-

Given A.P.,

• 17 , 24 , 31 , 38 …

First term (a) is 17.

Common difference (d) = 24 - 17 => 7

We know that :

• tn = a + (n - 1) d

Here n would be 11.

>> t11 = 17 + (11 - 1) 7

>> t11 = 17 + (10) 7

>> t11 = 17 + (10) × 7

>> t11 = 17 + 70

>> t11 = 87

Therefore, eleventh term in the sequence is 87.
