Question

Find the 10th term of ap 2, 7, 12,..........

Answer 1

Answer:

47

Step-by-step explanation:

7-2=5

12-7=5

Therefore, the sequence becomes,

2+5=7+5=12+5=17+5=22....

2,7,12,17,22,27,32,37,42,47

Answer 2

Answer:

• 47

Step-by-step explanation:

Given

• a (first term) = 2
• d (common difference) = 7 - 2 = 5
• number of terms (n) = 10

To find

• 10th term of the AP : 2, 7, 12 ....

Solution

↪ Sum of n terms of an AP:

• aₙ = a + (n - 1)d
• a₁₀ = 2 + (10 - 1)5
• 2 + 45
• 47

∴ a₁₀ (the 10th term) is 47.
