Find the seventh term in the sequence: 11, 13, 15, ...

The seventh term is 23.

Step-by-step explanation:

Step 1: This is an Arithmetic Progression 11, 13, 15 ...

Given, First term, a = 11

Step 2: Find Common difference, d = 13 - 11 = 2 Step 3: Formula for nth term in an AP, a (n) = a + (n-1) d Step 4: Substitute for 7th term, a (7) = 11 + (7 - 1) 2

= 11 + (6*2)

= 11 + 12 = 23
