Question

If a sequence follows the pattern $2.5n-10$, then find the ${10}^{th}$ term of the sequence.

• A. 5
• B. 10
• C. 15
• D. 20

Answer 1

The correct option is C

15

By substituting n = 10 in the given equation, we can find out the ${10}^{th}$ term i.e.,
$2.5x-10$ = (2.5 $\times$ 10) - 10
= 25 - 10
= 15
