2,11,20 find the t15
1 answer:
Answer:
128
Step-by-step explanation:
There is a common difference between consecutive terms, that is
11 - 2 = 20 - 11 = 9
This indicates the sequence is arithmetic with n th term
= t₁ + (n - 1)d
where t₁ is the first term and d the common difference
Here t₁ = 2 and d = 9 , thus
t₁₅ = 2 + (14 × 9) = 2 + 126 = 128

Option A:
Solution:
ABCD and EGFH are two trapezoids.
To determine the correct way to tell the two trapezoids are similar.
Option A:
AB = GF (side)
BC = FH (side)
CD = HE (side)
DA = EG (side)
So, is the correct way to complete the statement.
Option B:
In the given image length of AB ≠ EG.
So, is the not the correct way to complete the statement.
Option C:
In the given image length of AB ≠ FH.
So, is the not the correct way to complete the statement.
Option D:
In the given image length of AB ≠ HE.
So, is the not the correct way to complete the statement.
Hence, is the correct way to complete the statement.
